Note: I've installed the OpenMediaVault package on a quite fresh Debian Wheezy (7.6).
My Debian box was already configured to do PAM-LDAP auth: users from my LDAP server can SSH to it just fine and both getent passwd and getent group returns the LDAP users and groups.
On OMV WebGUI, the Group tab works: all my groups are displayed with correct members. However the Users tab seems to hangs: after a while the interface displays a modal window with the message:
An error has occured
As I want to benefits from OMV tools to set perms on Shared Folder I need to fix this.
I've tried to install the OMV LDAP plugin but it broke the PAM auth (could not SSH to the server using LDAP credentials anymore).
What log file should I look into to give you more useful infos on the problem?
