Mapping Ad account to Local Linux Group with Centrify Express on CentOS 6

Step 1. In order to add the AD User to the local User Group adduser command is not nsswitch aware and do not recognize a user not locally defined when adding someone to a group.

# vim /etc/group

.....
.....
users:x:100:user1,user2

Step 2: Edit /etc/centrifydc/centrifydc.conf Edit /etc/centrifydc/centrifydc.conf, uncomment and change the following parameter to true

# Merge local group membership from /etc/group into the Centrify group
# response for groups with the same name and gid.  This violates the NSS
# interface behavior and may have unexpected side effects, so it is
# disabled by default. You must run adreload to detect changes
# in the local group file.
#
adclient.local.group.merge:true

Step 3: Centrify Load and Flush

# adreload && adflush

Step 4: Check and verify. Logon as user1

$ id -a
uid=.........gid=.......... 100(users) .....................
