- GUI login fails with LDAP user if the domain is configured with SSL
- Assigning role to correct AD/LDAP user/group with wrong domain causes the user listing to fail

- Fixed issues
Takeover to a secondary cluster fails even after the primary cluster is completely powered off
The takeover to a secondary cluster fails even after primary cluster is completely powered off with the following error:
<cluster_name> cluster is either running or not completely down. Takeover of replication role is not permitted
In a rare scenario, the status of a remote cluster cannot be determined. The remote cluster status can be obtained from the console using the following command.
# haclus -display <remote_cluster_name> | grep ClusState
The takeover operation is permitted only when the remote cluster status is faulted or exited. But due to a bug, the remote cluster status shows the status as unknown even after the remote cluster is powered off. Also, if the remote cluster is powered off when the local cluster is down, the remote cluster status shows init. The takeover is not permitted in these scenarios. (4012004)
Workaround:
Run the following commands from the terminal of any node of the surviving cluster.
# /opt/VRTSnas/pysnas/bin/nso_replication.py --command online_nbu
# /opt/VRTSnas/pysnas/bin/nso_replication.py --command clear_host_cache
