Parallels Secure Workspace is unable to find nested security groups in the Active Directory (AD).
In the front end, the user may see this error (or a localized variant) when trying to sign in.
Authentication for user someuser failed: Unknown error.
For most use cases, leave the LDAP bind functions to their default settings.
In System Settings > Global > Domains, add and configure the Active Directory domain.
For each domain, it is possible to specify a bind function that determines how to bind with the Active Directory server and search for users and groups.
In case you have nested groups in your Active Directory, set Find Groups to one of these two methods:
- builtin.find_groups_by_token_groups (default)
This bind function allows finding groups recursively on your LDAP server.
