We're currently in the middle of an Openfire deployment, and I'm experiencing an issue on version 4.1.6 where no matter which format I use (I've tried CN=,OU=,DC=domainname,DC=org, the UPN, and everything in between for the openfire administrator account, and nothing. Test connection fails every time with the vague "check supplied credentials" error message. I know they credentials are correct; otherwise the account wouldn't be able to log in itself. Quick thought, can the name of the AD account that is the admin account have a space in it? Could that be the issue, I wonder? Because our Openfire administrator account does, in fact, have one. Any more info I can provide, please let me know, because this is driving me fifteen kinds of bonkers. Thanks for the hand in advance, guys; very much appreciated!
