Description

I am having issue in configuring LDAP group filter  to search the user under specific group,   my topology configuration looks like below :

Need to search only  under m_powerusers group.

<param name="main.ldapRealm.userSearchBase" value="dc=ds,dc=nb,dc=com"/> <param name="main.ldapRealm.userSearchFilter" value="(&(objectclass=*)(memberOf=cn=m_powerusers,OU=Applications,OU=Groups,DC=ds,DC=nb,DC=com))"/> <param name="main.ldapRealm.userObjectClass" value="person"/> <param> <name>main.ldapRealm.userSearchAttributeName</name> <value>sAMAccountName</value> </param>
