We are using BI server 4.5.0 which has been integrated to CAS and fetching roles from LDAP group and its subgroups.
RDBMS is Oracle.

When I assign permission to any ldap listed groups to available solutions, permission doesn't persist. When user logs in, he sees only "Loading..." message in solution listing area.

Configuring role in xml and resetting default permission works. But we need it to persist without this manual steps

Please let me know what information I can provide for further investigation.
