Description of problem:
pam_userdb stopped working after upgrade vom fc3 to fc4.


Version-Release number of selected component (if applicable):
pam-0.79-9.1

How reproducible:
Always

Steps to Reproduce:
1. setup /some/text/file with username\npassword 
2. run db_load -T -t hash -f /some/text/file /some/text/file.db
3. configure pam to use it: 
auth            required        pam_userdb.so db=/some/text/file
  

Actual Results:  login fails

Expected Results:  login should succeed

Additional info:

pam_userdb can e.g. be used with vsftpd. 

contents of /etc/pam.d/vsftpd:

auth            required        pam_userdb.so debug db=/etc/vsftpd_login
account         required        pam_permit.so
session         required        pam_permit.so


with pam_userdb.so from pam-0.79-9.1:

ymmv pam_userdb[20219]: Verify user `plonk' with password `samplepassword'
ymmv pam_userdb[20219]: password in database is [0x835d728]`samplepassword', len is 14

after replacing it with the FC3 one from pam-0.77-66.2.i386.rpm it works again:

pam_userdb[20204]: Verify user `plonk' with password `samplepassword'
pam_userdb[20204]: password in database is [0x8356928]`samplepassword', len is 14
pam_userdb[20204]: user 'plonk' granted acces


while testing, I also saw garbage added to the password:
password in database is [0x*******]`********^P', len is 8
password in database is [0x*******]`*************ogin.db', len is 13
