Yes I know...
I tried to migrate to 3.1.2 through the migrate procedure...
Meanwhile, we do not belong anymore the property.last file, due to the Security Policy of our company.
So I was not able to complete it...
Obviously, LDAP is running.
I checked the logs but I did not managed to find anything which could help us.
The server satus is OK.
But everything send 404 error.
I think now the only way to go through this probem, is to reinstall Gluu server.
