From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020607 Description of problem: When PAM is configured to use pam_ldap (e.g., in /etc/pam.d/system-auth) or the like), pam_ldap looks for libssl.so.2 and tries to load it. When it does, it finds an unresolved symbol: Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM unable to dlopen(/lib/security/pam_ldap.so) Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM [dlerror: /lib/libssl.so.2: undefined symbol: OpenSSLDie] Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM adding faulty module: /lib/security/pam_ldap.so This is a fairly serious bug, as it will prevent some people from logging in unless they have local /etc/passwd and shadow information on a given box. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: In /etc/pam.d/system-auth: auth required /lib/security/pam_env.so auth sufficient /lib/security/pam_ldap.so debug auth sufficient /lib/security/pam_unix.so likeauth nullok auth required /lib/security/pam_deny.so Make sure to upgrade to the latest OpenSSL. Then try to log in. Actual Results: Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM unable to dlopen(/lib/security/pam_ldap.so) Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM [dlerror: /lib/libssl.so.2: undefined symbol: OpenSSLDie] Aug 1 14:05:17 pcrgoerwit sshd[25322]: PAM adding faulty module: /lib/security/pam_ldap.so Expected Results: Should have seen nothing about unresolved symbols, and I should have been able to log in! Additional info: This bug should be fixed. It may result in people getting locked out of their machines - which is more than just inconvenient.
Okay, this bug is easily worked around: Run /sbin/ldconfig and restart any services that care about the PAM modules (like sshd).
