From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2 Description of problem: Bug 55193 shows issues with pam authentication when the network is down. These fixes do work (bug 55193), if /usr is mounted locally. We are running of a nfs mounted /usr, the pam modules are linked to shared libraries in /usr, so if the network is down not even root can login to the system. This is an issue for me, we cannot even log in to see the issue with networking. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Down network (or start with not network cable) try to login 2. Login with local password, loging fails Actual Results: No one can login Expected Results: Local users should still be able to login Additional info:
Could you please test which module makes the login fail for you? Especially could you test with pam_console commented out?
This bug report is incomplete, no response from the reporter.
Here are the pam modules linked to libraries in /usr pam_smbpass.so pam_ldap.so pam_krb5.so pam_krb5afs.so pam_console.so pam_cracklib.so
Yeah I know that, however I need to know which exact module makes the login fail for you. These modules aren't part of the basic pam package and you cannot expect them to work without network anyway: pam_smbpass.so pam_ldap.so pam_krb5.so pam_krb5afs.so This module is used only on password change -> no problem with login: pam_cracklib.so This module was modified not to link to libraries in /usr in the Fedora development - you can test it using the FC4Test3 release: pam_console.so
Great. I will test fc4. I think it will fix the problem, as I expected local logins to work wen the network was down. Thankyou.
