Working in an Active Directory (AD) environment many built-in groups have whitespaces in their name, e.g. "Domain Users".
Escaping these names in /etc/security/access.conf will not work.


The solution is to use the "listsep" option for . The domain name in this example is "INTERN.PRIV". To list several groups, just use the "," as separator.

pam-config --add --access
pam-config --add --access-listsep=,

/etc/security/access.conf :

+ :INTERN.PRIV\Domain Admins:ALL
- :INTERN.PRIV\Domain Users:ALL
+ :root:ALL

This ruleset allows root and members of the "Domain Admins"  group access to the system.
Caution: Whitespaces will now be interpreted as part of the name, therefore please check to remove all whitespaces, as in the example above, exept the ones in the user- or groupnames.
These rules are processed top-down. If the first rule processes that a user cannot login, the processing is stopped.

- :INTERN.PRIV\Domain Users:ALL
+ :INTERN.PRIV\Domain Admins:ALL
+ :root:ALL

This example will result in all domain users not being able to login. The first rule will be evaluated, and since the built-in Administrator user is in the group "Domain Users"
access is denied and the rule processing will be stopped.
