ldap://x.x.x.x:389/ Did not get a response from the MID server after waiting for 55 seconds

[RiteshSwarnakar]

Issue: LDAP "Test Connection" and "Browse" features can timeout, and LDAP Monitor may show Connection Statu...

Fix:  We tried the workaround they have mentioned i.e creating Business Rule to fix this, but unfortunately that did not work in our case. 

Resolution:  We did a clean and fresh installation of MID Server and configured it with LDAP server in the instance and it worked in our case. The error message is not appearing now.
