After successfully breaking my BESx box, I finally got the thing back up and running, only to find that I couldn’t login to the WebGUI. I don’t recall having touched the Java installs but in my attempt to get BESx back up and running I did all sorts.
Anyway, if you get this error: “The username, password, or domain is not correct. Please correct the entry.”

When logging in to the administration service (and you’re sure you have the correct username and password) then go in to AD and change the details on the user account to allow “Use Kerberos DES encryption types for this account”.

Then maybe you can login. Thanks to semi-anonymous Ryan Smith (here) for that fix.
Another option, which took me a few hours to figure out is to change the URL. The URL for the control panel is normally:
https://SERVERNAME.my.domain.dom:3443/webconsole/login
change this to:
http://SERVERNAME:3443/webconsole/login
and use the login credentials
- username: besadmin
- domain: my.domain.com
- password: ********
Also, check that the server time is correct. If it’s more than 5 mins out, you will get LDAP issues.
