Hi again,
It seems that there is a problem with the Blind Users role and the add to group features : i configured a user as he can see only a specific OU through blind users role (everyone with full scope and an exception for this user on the OU).
I can browse for a group through the Web UI and then add a new member, but if i want to use the add to group, i can select the user first but when i click next, the Web UI return "There are no groups to add 'My User' to." (Where My User stands for the real user name obviously).
Am i doing something wrong ?
