Fixes file descriptor leak none

Description Daniel Colascione 2005-11-18 21:32:35 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050920 Firefox/1.0.7 SUSE/1.0.7-0.1

Description of problem:
When the 'validate' flag is given to pam_krb5 in the PAM configuration, pam_krb5 leaks a file descriptor.

Version-Release number of selected component (if applicable):
pam_krb5-2.1.8-1

How reproducible:
Always

Steps to Reproduce:
1. Enable validate for pam_krb5
2. Use pam_krb5 in a process that doesn't die after using PAM (like saslauthd)
3. Use lsof to verify that the file descriptor is being leaked
  

Actual Results:  One file descriptor is leaked per authentication.

Expected Results:  No files should be leaked.

Note to self: the file handle is stored in the krb5_keytab structure, and the
call to krb5_verify_init_creds overwrites the one we're using when it creates
its own cursor.
