Troubleshooting: OIDC Password Grant Type Does Not Honor Group Restrictions

Version Affected: All
 
 

Overview

When using the OIDCToken endpoint with the Password grant type, Group Restriction checks are not performed.

Cause

Group Restriction and Adaptive Authentication settings cannot be applied to OIDCToken, since it normally handles anonymous requests from OAuth servers.

Resolution:

You can work around this by using a different search filter on the Data tab, so that only users in a specific group can authenticate:

1. Click the Data tab.
2. Edit the search filter so it looks something like this:

(&(samAccountName=%v)(memberof=CN=ExampleGroup,OU=Groups,DC=example,DC=local))

This example only allows users who are a member of a group named ExampleGroup, in the Groups organizational unit of the example.local domain -- substitute your own group, OU, and domain.

3. Save.
