[CentOS] ldap: adding user to multiple groups

Hi all,

Not having much luck adding a user to more then 1 group in OpenLDAP  
thats provided in Centos.

Any suggestions to have the outcome of having a user belong to  
multiple groups?

Should I create a new group that has multiple GIDs and assign a user  
to that new group?  If so, how? :)

Thanks in advance.
