Unable to authenticate with AD user after making AD group entry in access.conf (pam_access.so) file

Issue

• While using pam_access.so module and access.conf file to limit access just to Active Directory users, able to archive it if explicit mention
  AD user on access.conf file, but if I try to use a group in stead of using user's name it's not working.
