Re: [suse-security] Why is passwd truncating passwords

another thing that may help even thought the file comments say that is ignored if using md5 or blowfish is

pc> cat /etc/login.defs | grep PASS_MAX_LEN

PASS_MAX_LEN 255

The comments for this setting say

#
# Number of significant characters in the password for crypt().
# Default is 8, don't change unless your crypt() is better.
# Ignored if the "md5" or "blowfish" option is given to the
# pam_pwcheck module.
#

but it may be worth a try if everything else fails.

Hi all,

This must be a bug in passwd.

i'm running 8.2. try using md5 too see if it's a bug in the blowfish

password: blowfish nullok
Manual says it will truncate at 97 or so chars.

72 I just reread


It truncates with DES, MD5 and blowfish
When using yast to modify a user password +8 long pws work.

Explicitely setting an allowable password length seems to work however.

# cat pam_pwcheck.conf | grep maxlen
password: minlen=6 maxlen=16 cracklib md5 nullok
