Omnibus installations use /etc/gitlab/gitlab.rb; Helm and Docker use their deployment-specific configuration paths.
What “multiple providers” means in GitLab
GitLab Self-Managed uses OmniAuth for external authentication. A provider entry connects GitLab to one registered application at an identity service. Common supported strategies include Google (google_oauth2), GitHub (github), generic OAuth 2.0, Azure v2, OpenID Connect (openid_connect), and SAML.

Each entry needs its own provider name, client credentials, and provider-specific arguments. If you configure Google and GitHub, those are two different provider entries. If you configure two independent OIDC services or two SAML tenants, each instance also needs a unique name and login label. Adding two entries that both represent the same external authentication provider is not a supported way to create separate identities.
Plan the identity model before editing GitLab
Inventory the protocols and provider names
Write down every sign-in button you intend to expose and classify it as Google OAuth, GitHub OAuth, generic OAuth 2.0, OIDC, SAML, or another strategy supported by your GitLab version. Use the exact strategy and provider names from GitLab’s supported-provider documentation. Names are not cosmetic: they appear in callback paths, allowlists, stored identities, and troubleshooting output.

Decide how accounts should be created
Before enabling a button, decide whether a successful external login may create a GitLab account automatically. The important controls are:
allow_single_sign_on(orallowSingleSignOnin Helm values) identifies providers allowed to create or sign in users through single sign-on.block_auto_created_userscontrols whether newly created accounts wait for administrator approval. Blocking is the safer default when membership must be reviewed.auto_link_userdetermines whether a provider identity can be linked to an existing GitLab account using a matching email address. Treat automatic linking as a deliberate trust decision.external_providersmarks accounts from selected providers as external, which can restrict access to internal projects and features according to GitLab’s external-user rules.- Profile synchronization settings determine whether name, email, username, or other profile attributes are refreshed from the identity service.
Also keep a recovery administrator login that does not depend on the providers you are changing. A callback or configuration mistake should not remove your only path into the instance.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesRegister an application at each identity provider
Create a separate application registration for GitLab at Google and record its client ID and client secret. Add the exact redirect URI generated for your GitLab host and the google_oauth2 strategy. The host, scheme and path must match the address users actually reach; differences such as HTTP versus HTTPS, an alternate hostname, or a missing path cause a redirect-URI error.
GitHub
Create an OAuth App and copy its client ID and client secret into your deployment’s secret mechanism. GitHub’s callback must include the full path /users/auth/github/callback, not merely the GitLab hostname. For example, the registered value follows the form https://gitlab.example.com/users/auth/github/callback, with your real GitLab host substituted.
OIDC and generic OAuth 2.0
Record the issuer or discovery information, authorization and token endpoints when required, scopes, and the claims that identify a user. At minimum, confirm which claim supplies a stable subject identifier, which supplies email, and which supplies a display name. A username claim must be unique within GitLab; collisions can prevent reliable account identification.

SAML
For each SAML identity service, create a distinct provider name and button label. The ACS callback path must contain the matching provider name. If just-in-time account creation is enabled, every SAML provider name must also be included in the single-sign-on allowlist.
Configure two providers on an Omnibus Linux installation
For the Linux package, provider definitions belong in /etc/gitlab/gitlab.rb. The following illustrates the structure for Google and GitHub; obtain the exact provider arguments and callback values from the current GitLab integration guidance for your version.
gitlab_rails['omniauth_providers'] = [
{
name: 'google_oauth2',
app_id: 'GOOGLE_CLIENT_ID_FROM_SECRET_STORE',
app_secret: 'GOOGLE_CLIENT_SECRET_FROM_SECRET_STORE'
},
{
name: 'github',
app_id: 'GITHUB_CLIENT_ID_FROM_SECRET_STORE',
app_secret: 'GITHUB_CLIENT_SECRET_FROM_SECRET_STORE'
}
]
# Add only the providers you have approved for account creation.
# Configure account-linking, approval, external-user and profile-sync
# settings according to your identity policy.Do not commit real secrets to a public repository or paste them into support tickets. Restrict access to gitlab.rb and use the secret-management facility appropriate to your deployment.
- Edit
/etc/gitlab/gitlab.rband add one object for each provider. - Use unique names and include the intended names in the relevant single-sign-on and external-provider settings.
- Save the file, then apply it with
sudo gitlab-ctl reconfigure. - Open the GitLab sign-in page and verify that the expected buttons appear. If a button is absent, check the provider definition and the administrator’s sign-in restrictions.
Configure providers with Helm
GitLab Helm deployments do not read the Omnibus file. Set the OmniAuth values under global.appConfig.omniauth in your chart values, defining one provider object per external service. Preserve unique names for repeated OIDC or SAML strategies and keep credentials in Kubernetes Secrets or the chart’s supported secret mechanism rather than plain values files.
- Update the values file or secret references with the provider list and account-provisioning controls.
- Check that each callback uses the externally reachable GitLab host and the correct provider name.
- Apply the change with your normal
helm upgradecommand for the release. - Wait for the webservice pods to roll out, then test each button and inspect the resulting account state.
Configure providers in Docker or a source deployment
Docker installations commonly pass the GitLab configuration through GITLAB_OMNIBUS_CONFIG. Put the equivalent OmniAuth provider objects and policy settings there, protect the environment values, and restart or recreate the container so the configuration is loaded. Source installations use the configuration mechanism for that deployment and likewise require a restart or redeploy after changing OmniAuth settings.

Do not assume that editing a host-side file changes a running container. Confirm the effective configuration inside the deployed GitLab instance before testing.
Configure more than one OIDC provider
Two OIDC services cannot safely share an indistinguishable configuration. GitLab’s documented pattern repeats the openid_connect entry but assigns an explicit strategy_class, a unique provider name and label, and a different issuer or discovery endpoint to each service.
# Illustrative shape; use the exact strategy-class and argument names
# documented for your GitLab version.
{
name: 'oidc_team_a',
label: 'Team A',
strategy_class: 'THE_OPENID_CONNECT_STRATEGY_CLASS',
args: {
name: 'oidc_team_a',
issuer: 'https://issuer-a.example',
scope: ['openid', 'profile', 'email']
}
}
{
name: 'oidc_team_b',
label: 'Team B',
strategy_class: 'THE_OPENID_CONNECT_STRATEGY_CLASS',
args: {
name: 'oidc_team_b',
issuer: 'https://issuer-b.example',
scope: ['openid', 'profile', 'email']
}
}The two entries must produce different callback paths and must not reuse an issuer, client registration, or provider name accidentally. Verify the sub (subject) value and username claim returned by each service before enabling automatic linking.
Configure more than one SAML provider
Use distinct names such as saml and saml_2, and give each a clear login label. The callback URL for each entry must contain its matching name, so a callback for saml_2 must not be sent to the saml endpoint. Add both names to the single-sign-on allowlist when you want just-in-time account creation from both services.
Recommended Free Tools
Keep the entity IDs, signing certificates, and attribute mappings separate. A successful SAML assertion from the wrong tenant can otherwise create an account under an unexpected provider identity.

Apply a deliberate account and profile policy
Approval and external status
For an organization-controlled GitLab, enable automatic account creation only for providers whose membership is trusted. Set block_auto_created_users when an administrator must approve newcomers. Decide separately whether those users are external; approval status and external status solve different problems.
Email matching and linking
Existing users can link a provider from Profile → Access → Password and authentication. Automatic email linking is convenient but should be limited to providers that verify email ownership reliably. If two services issue the same email to different people, automatic linking can associate the wrong external identity.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Username claims and profile synchronization
Choose a stable, unique username claim when setting a custom gitlab_username_claim. Synchronize only attributes your organization wants the identity provider to control. Changes to a display name are usually harmless; changes to a username or email can affect account discovery, notifications, and administrative workflows.
Control which buttons users can use
After configuration, administrators can selectively enable or disable configured providers under Admin → Settings → General → Sign-in restrictions. This lets you keep a provider definition available for testing or existing linked accounts while temporarily hiding its sign-in button. A hidden button does not by itself erase stored identities.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Test every provider before announcing the change
- Use a controlled account at the external provider, preferably one that is not already linked to GitLab.
- Start from the GitLab sign-in page and select exactly one provider button.
- Confirm that the browser is sent to the intended provider and returns to the same GitLab host over HTTPS.
- Check that the callback path contains the expected provider name and that no redirect-URI or state error appears.
- Inspect the resulting GitLab account: username, email, internal or external status, linked identity, and approval state.
- Repeat with an existing GitLab user who links the provider from the profile settings.
- Test a denied authorization, an unapproved account, and a provider account with a different email domain so policy failures are understood before production use.
Record which external subject or identity maps to each GitLab user. This mapping is essential if you later replace an OAuth App, rotate applications, or move between identity tenants.

Troubleshoot common failures
The provider button is missing
- Confirm the provider object is under the correct configuration key for your deployment type.
- Check that the configuration was applied with
gitlab-ctl reconfigure, a successful Helm upgrade, or a container restart. - Look for the provider in Admin → Settings → General → Sign-in restrictions; an administrator may have disabled it.
- Verify the provider name is spelled consistently in the definition and allowlists.
Redirect URI or callback errors
- Compare the registered URI character-for-character with the URL GitLab uses, including scheme, hostname, port, path and trailing characters.
- For GitHub, ensure the path is the complete
/users/auth/github/callbackpath. - For OIDC and SAML, confirm that the callback path uses the unique provider name for that instance.
- Check reverse-proxy headers and the externally configured GitLab host if GitLab generates an internal hostname.
Users are created unexpectedly or remain pending
Review allow_single_sign_on, block_auto_created_users, and auto_link_user together. A provider can be configured correctly yet produce a pending account because approval blocking is enabled, or link to an existing account because email-based linking is enabled. Change one policy at a time and retest with a controlled identity.

Inspect the subject and username claims returned by the provider. A custom gitlab_username_claim must be unique and stable. Do not use a mutable display name as the identity key. Correct the claim mapping before enabling automatic linking for more users.
OIDC works for one service but not the other
Compare the two entries for a missing strategy_class, duplicated provider name, reused issuer, or a discovery endpoint belonging to the wrong tenant. Each OIDC service needs its own issuer or discovery data and a unique name and label.
Replacing an OAuth application without stranding users
GitLab stores the external identity as an extern_uid associated with a provider. Replacing an application or changing the upstream provider can alter that identity value. If the stored value and the new assertion no longer match, returning users may appear to GitLab as new users or lose their link.
- Export or document the current provider-to-user mapping before making the change.
- Keep the old application available while testing the replacement, if the identity service permits it.
- Compare the old and new subject or external-ID values for representative users.
- Coordinate required identity updates through the Users API or Rails console using an approved maintenance procedure.
- Test existing linked users, new users and administrators before retiring the old application.
Do not model the replacement as a second independent provider when it is actually the same external authentication service. GitLab’s identity model permits only one provider per unique external authentication provider.
