Description Paolo Penzo 2007-02-02 12:50:31 EST
pam_krb5.so has missing symbols due to lack of linkage to libpam (see bug #183363).

A test plan / code block would be very useful for QA.

Simple test for modules with undefined symbols which don't link with libraries which provide them.

The bug is pretty straightforward: if you use dlopen() to open the library, and
you're not already linked to libpam, it fails because there are symbols in
libpam on which the module depends.  If running this script against the module
like so:
  ./dlopen.sh ./pam_krb5.so
fails while running it like so:
  ./dlopen.sh ./pam_krb5.so -lpam
succeeds, then you have the behavior described as in the report.  The desired
behavior is for the script to succeed in both cases.
