LDAP user role mapping


I currently have NXRM hooked up to my LDAP server for authentication and authorization purposes. I have role mapping working as well. However, one thing i noticed is that when i assign a new group or move user to another group in my LDAP server, the rights for that user in NXRM does not seems to change at all.

For example, i have a sysadmin group that allow user to administer NXRM. When i move an user from dev group to sysadmin group, i expect the user to gain admin permission but nothing seems to change even after waiting for a day or two. When i check the user mapping test results, the roles for that user remains unchanged and NXRM permssion remains the same as well.

Am i missing something somewhere or not understanding something correctly?
