Package: libcap2-bin
Version: 1:2.19-1
Severity: important

Since the latest upgrade I see a lot of PAM error messages in my log:

Aug  2 22:26:52 sol authdaemond: PAM unable to dlopen(/lib/security/pam_cap.so): /lib/security/pam_cap.so: undefined symbol: pam_get_item
Aug  2 22:26:52 sol authdaemond: PAM adding faulty module: /lib/security/pam_cap.so

They seem to appear every time I login on my IMAP server (courier-imap-ssl).

There is a similar bug report at Launchpad [1]. I rebuilt the package with the
attached patch and the messages stopped to appear.

I am still having this problem and I see that this bug was resolved for i386 only.  When can we expect the amd64 and other platforms to get this update?  The mirrors (mirrors.kernel.org, us.debian.org) are still showing "Version: 1:2.19-1" instead of the updated one 2.19-2 for amd64.  Thanks!

Date: Mon, 9 May 2011 08:40:30 -0500

The fix for bug 591410 appears to be have been dropped from
libcap2 1:2.20-1, which gives me:

May  8 22:51:08 debian authdaemond: PAM unable to dlopen(/lib/security/pam_cap.so): /lib/security/pam_cap.so: undefined symbol: pam_get_item
May  8 22:51:08 debian authdaemond: PAM adding faulty module: /lib/security/pam_cap.so
May  8 22:51:08 debian authdaemond: pam_unix(imap:auth): authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=  user=serge

In fact, -lpam is no longer being added to pam_cap's LDLIBS.
