Evaluate condition against LDAP with ulang

Hi people, I have implemented a Freeradius sever running OK that authenticate against LDAP. Firstly, I have a LDAP tree with users under groups, such as: CN=Network,OU=Employess,DC=company,DC=com and my evaluating condition wit ulang was: if (LDAP-Group == Network) And the authentication was OK. But now, the LDAP administrators has modify the LDAP tree and now the users are under the OU as below: OU=Employess,DC=company,DC=com How can I evaluate the condition "if the user is under OU=Employees" ??? Because if I use if (LDAP-Group == Employees), it doesn't authneticate. Thanks a lot, regards !!!
