Product and Software: This article applies to all Aruba controllers and ArubaOS 3.4.x and later.


The LDAP filter character limit is 256.

The character limit of the LDAP filter is important when you need to configure the LDAP server on the Aruba controller. This filter is where the object class is used that depends on the OUs and DCs.

Sample Filter field:


(&(objectclass=inetorgperson)(|(memberOf=cn=Wirele ssAccess,OU=Security,OU=Groups,DC=ad-test,DC=testdc,DC=org)(memberOf=cn=WirelessAccessCus tom,OU=Security,OU=Groups,DC=ad-test,DC=testdc,DC=org))(!(memberOf=cn=WirelessAccess Denied,OU=Security,OU=Groups,DC=ad-test,DC=testdc,DC=org)))
