LDAP user overlap

Hi,

We are providing SSLvpn access to 2 different customers. Both are using LDAP integrated users based on their AD with remote groups. However we are now in a situation that we have some overlapping usernames. Apparantly Fortigate doesn't allow this, and the login only works for the first user.

Is there any workaround for this? I've tried adding the domain name to the username, but this doesn't work.

Is this something that would be somewhere on the roadmap to be fixed?

Thanks
