User gets permission denied when searching with paging in the Red Hat Directory Server ?

Issue

• We have a permission denied on a query we try to execute with paging enabled. When we do it with the directory administrator, everything work fine.
  The query we try to do is on the "ou=People,dc=external,dc=example,dc=com" subnodes. And the ACI for our user on "dc=external,dc=example,dc=com" branch is :

(targetattr = "*") (version 3.0;acl "DESCRIPTION";allow (all)(userdn = "ldap:///uid=test-admin,ou=People,dc=example,dc=com");)

Is there a specific right to grant to enable paging for a regular user ?
