[<sigh> I'm sure this has been dealt with many times before, so my apologies in advance for posting what's likely a FAQable question...] On my RH 6.2 system, I've started seeing PAM errors of the form: Dec 11 14:28:03 xxx login: PAM unable to dlopen(/lib/security/pam_console.so) Dec 11 14:28:03 xxx login: PAM [dlerror: /usr/lib/libglib-1.2.so.0: symbol getpwuid_r, version GLIBC_2.1.2 not defined in file libc.so.6 with link time reference] Dec 11 14:28:03 xxx login: PAM adding faulty module: /lib/security/pam_console.so I'm given to understand this is related to a mismatch between the installed pam build and the system's installed version of glibc. However, what I'm running for each of those things are AFAIK the most recent versions applicable to RH 6.2, _all_ just pulled off ftp.redhat.com (_all_ from the same RPM directory) and _all_ just now re-installed at the same time: [root@xxx 14:30:51 /var/log]# rpm -q -a | egrep "pam|libc" libc-5.3.12-31 glibc-devel-2.1.3-22 pam-0.72-20.6.x glibc-2.1.3-22 So unless RedHat's ftp archive is internally inconsistent, these should play nice together. But they're not. Ideas? thanks, /D/
