Hey everyone - trying to get my Proxmox cluster connected to JumpCloud's LDAP service and I keep getting an "invalid LDAP packet (500)" when trying to add my bind user. I don't see anything in my firewall logs that shows a problem and I'm not sure where to look in Proxmox's logs. Anyone been able to successfully get this working? PVE 8.3.3
 
Hi, I had the same erro until I figured out two key points:

For the Base Domain Name field, you need to fill it in like this:
ou=Users,o=32932ORGHASHHERE,dc=jumpcloud,dc=com
And for the User Attribute Name field, it needs to be either uid or email. In my case, it was uid.
This field determines which attribute users will use to log in.
Finally, in Sync Options under Bind User (bind_dn), you should enter something like:
uid=userHere,ou=Users,o=32932ORGHASHHERE,dc=jumpcloud,dc=com

Test the connection, and if it works, remember to do the first manual sync afterwards.
