ldap connections remain open in IPA (IdM)

Solution Verified - Updated -

Issue

The IPA server has a many LDAP connections open to the same server despite clients on reporting 1 connection.

Using netstat/ss it shows only one ESTABLISHED connection from the client to server, and the server reports many ESTABLISHED connections to the client.

IPA server:
