# SCIM provisioning using SAML SSO for Groups **(SILVER ONLY)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/9388) in [GitLab.com Silver](https://about.gitlab.com/pricing/) 11.10.
System for Cross-domain Identity Management (SCIM), is an open standard that enables the
automation of user provisioning. When SCIM is provisioned for a GitLab group, membership of
that group is synchronized between GitLab and the identity provider.
GitLab's [SCIM API](../../../api/scim.md) implements part of [the RFC7644 protocol](https://tools.ietf.org/html/rfc7644).
Currently, the following actions are available:
- CREATE
- UPDATE
- DELETE (deprovisioning)
The following identity providers are supported:
- Azure
## Requirements
- [Group SSO](index.md) needs to be configured.
## GitLab configuration
Once [Single sign-on](index.md) has been configured, we can:
1. Navigate to the group and click **Settings > SAML SSO**.
1. Click on the **Generate a SCIM token** button.
1. Save the token and URL so they can be used in the next step.
## Identity Provider configuration
### Azure
The SAML application that was created during [Single sign-on](index.md) setup now needs to be set up for SCIM.
1. Check the configuration for your GitLab SAML app and ensure that **Name identifier value** (NameID) points to `user.objectid` or another unique identifier. This will match the `extern_uid` used on GitLab.
1. Set up automatic provisioning and administrative credentials by following the
[Provisioning users and groups to applications that support SCIM](https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/use-scim-to-provision-users-and-groups#provisioning-users-and-groups-to-applications-that-support-scim) section in Azure's SCIM setup documentation.
During this configuration, note the following:
- The `Tenant URL` and `secret token` are the ones retrieved in the
[previous step](#gitlab-configuration).
- Should there be any problems with the availability of GitLab or similar
errors, the notification email set will get those.
- It is recommended to set a notification email and check the **Send an email notification when a failure occurs** checkbox.
- For mappings, we will only leave `Synchronize Azure Active Directory Users to AppName` enabled.
You can then test the connection by clicking on **Test Connection**. If the connection is successful, be sure to save your configuration before moving on. See below for [troubleshooting](#troubleshooting).
#### Configure attribute mapping
1. Click on `Synchronize Azure Active Directory Users to AppName`, to configure the attribute mapping.
1. Click **Delete** next to the `mail` mapping.
1. Map `userPrincipalName` to `emails[type eq "work"].value` and change it's **Matching precedence** to `2`.
1. Map `mailNickname` to `userName`.
1. Determine how GitLab will uniquely identify users.
- Use `objectId` unless users already have SAML linked for your group.
- If you already have users with SAML linked then use the `Name ID` value from the [SAML configuration](#azure). Using a different value will likely cause duplicate users and prevent users from accessing the GitLab group.
1. Create a new mapping by clicking **Add New Mapping** then set **Source attribute** to the unique identifier determined above, **Target attribute** to `id`, **Match objects using this attribute** to `Yes`, and **Matching precedence** to `1`.
1. Create a new mapping by clicking **Add New Mapping** then set **Source attribute** to the unique identifier determined above, and **Target attribute** to `externalId`.
1. Click the `userPrincipalName` mapping and change **Match objects using this attribute** to `No`.
Save your changes and you should have the following configuration:
NOTE: **Note:** If you used a unique identifier **other than** `objectId`, be sure to map it instead to both `id` and `externalId`.
1. Below the mapping list click on **Show advanced options > Edit attribute list for AppName**.
1. Leave the `id` as the primary and only required field.
NOTE: **Note:**
`username` should neither be primary nor required as we don't support
that field on GitLab SCIM yet.
1. Save all the screens and, in the **Provisioning** step, set
the `Provisioning Status` to `On`.
NOTE: **Note:**
You can control what is actually synced by selecting the `Scope`. For example,
`Sync only assigned users and groups` will only sync the users assigned to
the application (`Users and groups`), otherwise, it will sync the whole Active Directory.
Once enabled, the synchronization details and any errors will appear on the
bottom of the **Provisioning** screen, together with a link to the audit logs.
CAUTION: **Warning:**
Once synchronized, changing the field mapped to `id` and `externalId` will likely cause provisioning errors, duplicate users, and prevent existing users from accessing the GitLab group.
## Troubleshooting
### Testing Azure connection: invalid credentials
When testing the connection, you may encounter an error: **You appear to have entered invalid credentials. Please confirm you are using the correct information for an administrative account**. If `Tenant URL` and `secret token` are correct, check whether your group path contains characters that may be considered invalid JSON primitives (such as `.`). Removing such characters from the group path typically resolves the error.
### Azure: (Field) can't be blank sync error
When checking the Audit Logs for the Provisioning, you can sometimes see the
error `Namespace can't be blank, Name can't be blank, and User can't be blank.`
This is likely caused because not all required fields (such as first name and last name) are present for all users being mapped.
As a workaround, try an alternate mapping:
1. Follow the Azure mapping instructions from above.
1. Delete the `name.formatted` target attribute entry.
1. Change the `displayName` source attribute to have `name.formatted` target attribute.
