AD Connection Error

Ignition
1

I was hoping to maybe get some pointers on this one.. Trying to set up a second user source. I'm not sure if the error log means the server cant connect to the AD or if there is a password issue as it says LDAP connection has been closed, as if it was open trying to access it. All usual IT ports, forwarding etc has been done, or so I'm led to believe.

java.lang.Exception: Failed connecting to LDAP server.

Did you enable the specific port in your firewall rules?

As far as I'm aware IT done all the necessary steps. We have two locations, one was working and one wasn't. They said it was the same set up.

Then out of the blue I noticed its pulled the users so its working now but noticed in the logs every 5-6 mins it failed to fetch again. I've increased the cache time so its not polling every 60 seconds.

IT said they changed nothing so unsure why it wasn't working initially. I cant tell from the original log error what the actual problem was.
