Continuing on from https://blog.davekoelmeyer.co.nz/2011/11/19/pam-ldaps-and-policykit-weirdness-in-ubuntu-10-04-x86/, the second problem I have encountered with my test LDAP how-to is when LDAP users attempt to use a Policykit enabled application and have their otherwise valid credentials rejected.
In OpenDJ, my LDAP accounts are assigned the gidNumber attribute value of 119, which would place them into the admin group on Ubuntu and consequently allow them to make use of sudo and other applications requiring elevated privileges. Works great, except when using an application such as Ubuntu Software Center which makes use of Policykit.
Note that this is encountered when LDAP authentication is carried out regardless of whether SSL (LDAPS) is configured or not, but if it is then you have the added bonus of the local administrator account not being able to authenticate either…
