Viewer groups not filters with LDAP filter

[yvangodard]

In our Rattic instance, we use LDAP auth + a filter on LDAP groups (to show only specific LDAP groups on Rattic).
The LDAP filter works fine on LDAP principal group, but, when adding a new password, all LDAP groups appear in the Viewer groups list selector.
This list should be the same as principal LDAP groups and may be filtered as well.
