Description John T. Rose 2007-09-18 13:33:38 EDT
Description of problem:

consider an entry like

auth sufficient /lib/security/$ISA/pam_succeed_if.so user in redhat:hat

this will succeed for user redhat and fail for user hat

switching these around like

auth sufficient /lib/security/$ISA/pam_succeed_if.so user in hat:redhat

will succeed for both user redhat and for user hat

Version-Release number of selected component (if applicable):

appears broken on both rhel4 and rhel5 (didn't check anything older than that)

How reproducible:

should be obvious from above description

Steps to Reproduce:
Actual results:

Expected results:

Additional info:

take a look at the evaluate_inlist() function in pam_succeed_if.c and the cause
should be fairly easy to see

Here is a patch that seems to fix this for my case ... not sure about all other
possible uses of the operator...
