Setting Umask for LDAP (Windows AD)users

Hi

We have just integrated our RHEL 6.6 to our LDAP server every thing is working fine .But it seems like all LDAP users are getting a different UMSAK than the one specified in the /etc/profile..
How do i change this .Where are these LDAP user getting that UMASK setting from ,
Any idea
