Steps to reproduce:
1. Enable the LDAP service according to the docs
2. Make sure it doesn't work (for instance, providing a wrong parameter)
The system locks down, because the loop that checks whether the services are working or not will receive an exception for each and every service polled. After a while, all the services are marked as "not responding" and the whole system blocks.
We cannot get users from the LDAP server, but apart from that the system works properly
Workaround (if any):
