AD/LDAP domain unreachable alerts do not get cleared after the AD/LDAP server is deleted

When a new AD/LDAP server is added, if the domain is not reachable from the node, the following alerts are generated in the GUI:

Domain XXX is not reachable from node YYY.

If the server which is not reachable from the node is deleted, all the pending alerts should get cleared from the GUI. But this does not happen and the alerts are visible in the Alert management screen. (IA-39890)

Workaround:

There is no workaround to clear these alerts from the GUI. You can ignore the alerts based on the time stamps.
