Subject: Jumbo patch breaks "--users=<uid>" for pwdump
Hey guys,
During testing we noticed a little oddity today between the standard
John release and the -jumbo release when requesting UID vs. Username in
the --user option with PWDUMP files. For example:
Latest 1.7.9-jumbo-5 downloaded today:
root@...ckah:~/jtr/test-hashes/pwdump#
~/jtr/1.7.9/john-1.7.9-jumbo-5/run/john -users=500 *-pwdump -show -fo:lm
0 password hashes cracked, 0 left
root@...ckah:~/jtr/test-hashes/pwdump#
~/jtr/1.7.9/john-1.7.9-jumbo-5/run/john -users=500 *-pwdump -show -fo:nt

We tested the Unix passwd format and that works as it should, only
Windows formats seem to be affected.
