Java Time Out errors using SSO?


#1

Hi all,

I got my Linux server running Openfire 3.3.2 using SSO, but now I am getting weird Java timeout errors in the Debug log and SSO no longer works. Here are my environment specs:

Openfire Version: 3.3.2

Server OS: Red Hat Enterprise Linux 4

Directory: Windows 2003 AD

Spark version: 2.5.6

Like I said, SSO was working. But now SSO no longer work. Spark just sits there for a while and the errors out with the standard “cannot connect, check your principle” message. Typing in the username and password works, but SSO fails. Here is the error sequence when I try to sign on using SSO. If any other details are needed, please let me know. Thanks!

Anything in the spark logs?

Yes, there are some things in the error log. Here is it:

Well, I rebooted the Linux server and now SSO works. That’s weird. I know I probably did something to cause the error, but I can’t imagine what it was. I didn’t make any major changes to the Openfire server, just modifying options in the web GUI. I even restart the openfire service multiple times, but the problem only went away when I rebooted the server. Odd.

Any clues as to what it could have been? If not, I’ll just keep an eye on it. Hopefully the problem won’t return.
