Dear Maintainer,

I've installed libpam-radius-auth, ran pam-auth-update and selected
"Radius Authentication" checkbox.  It added following line to
/etc/pam.d/common-auth:

auth	[success=1 default=ignore]    pam_radius_auth.so use_first_pass

And following line to /etc/pam.d/common-account:

account	[success=ok new_authtok_reqd=done ignore=ignore user_unknown=ignore authinfo_unavail=ignore default=bad] pam_radius_auth.so

After that, if I try to login or "su - user" I get an error message
saying "Module is unknown" and see messages like the following on logs:

PAM unable to resolve symbol: pam_sm_acct_mgmt

After that it's impossible to login to the system.
