SUSE Linux Enterprise Server 11 Service Pack 1


Unable to login through GUI (runlevel 5) after updating pam-modules to version 11-1.14.1
Trying to login will show the following error: "Error in service module"
Runlevel 3 login works fine


To solve this issue perform the following steps:
  • Reboot server in runlevel 3
  • Downgrade pam-modules with the following command: "zypper in pam-modules-11-1.6.15"
  • Select option 1 to downgrade pam-modules
  • Switch to runlevel 5
A new version of pam-modules (11-1.16.1) will be released shortly that will solve this issue.
