After upgrade can't log in via web


#1

After running the most resent update to Univention Corporate Server 4.2-1 errata139 we are no longer able to log into any UCS via the web gui.

We get this error:

The current session is not valid with your IP address for security reasons. This might happen after switching the network. Please login again.

However our network has NOT changed. This occurs on Master, Backup, Slave and Member servers.

Rebooting does not cure this issue…now we can only manage our servers via SSH/CLI.

The log management-console-web-server.log shows:
The sessionid (ip=69.78.235.132) is not valid for this IP address (69.78.235.133)
17.08.17 10:34:52.686 MAIN ( WARN ) : The sessionid (ip=69.78.235.132) is not valid for this IP address (69.78.235.136)

and management-console-server.log shows:

After restarting UCM by…
/etc/init.d/univention-management-console-server stop
/etc/init.d/univention-management-console-web-server stop
then
/etc/init.d/univention-management-console-server start
/etc/init.d/univention-management-console-web-server start

I get this when trying to login as Administrator

There is no module available for the authenticated user Administrator.
