Pam-list Digest, Vol 18, Issue 3

[Raj Gautam]

I think I worked it out.
I boot up in single user mode. got the root shell.
* Reinstalled the libpam-modules, libpam0g, libpam-runtime. 
  #apt-get install --reinstall libpam-modules
  But it didn't work.
* I had 0.76-22, but compiled 0.80 which messed up the system.
* I found 3 files (libpam*.so) in /lib directory pointing to
libpam*.so.0.80. So I changed them to point libpam*.so.0.76 (old pam).
* Now it seems to be working.

Thank you Igmar for telling me to login in single user mode
