Users who have a login right assigned through membership in an Active Directory (AD) group and the centrifydc.conf parameter, pam.allow.group, randomly lose that right. These users are denied login. This is observed when executing adquery user <username>
# adquery user tetsu
The login shell for the user is changed to disallow the login.
A feature was introduced in DirectControl 5.5.1 that rebuilds group membership entries in the DirectControl cache when the group membership is refreshed. The group membership list is not rebuilt correctly. Users are not seen as members of the group and therefore, they lose the right assigned to the group.
The work-around is to disable the feature that rebuilds the group membership list.
1) Add the following parameter to /etc/centrifydc/centrifydc.conf
2) Stop and restart the adclient
