Editing the LAM configuration manually
In the /usr/lib/methods.cfg file, add the following lines to enable authentication through the Centrify agent and Active Directory:
CENTRIFYDC: program = /usr/lib/security/CENTRIFYDC program_64 = /usr/lib/security/CENTRIFYDC64 options = noprompt
In the /etc/security/user file, you need to change the SYSTEM attribute for your users. The easiest way to do this is to change the SYSTEM attribute in the “default” stanza. For example:
... SYSTEM = “CENTRIFYDC OR CENTRIFYDC[NOTFOUND] AND compat” ...
In addition, if any user has an explicit setting for the SYSTEM attribute, you should remove the setting. For example, by default, the root account has an explicit SYSTEM setting, so you should delete this line or comment it out.
