Maximum Password Length: does not work

F Verschuren — Wed, 12 Dec 2007 12:34:49 GMT

on a trusted system I have configgured is sam:

Maximum Password Length: 12

see alsow:
[:/tcb/files/auth/system]# grep u_maxlen default
:u_minchg#86400:u_maxlen#12:u_exp#7862400:u_life#16934400:\
[:/tcb/files/auth/system]#

So now I can create a passwd of 12 caracters and that works fine, if I type in the first 11 caracters is wil not work... however if i use a 8 caracter passwd the passwd wil alsow work if I type in extra caracters... is there a fix for this.
I dit a find on the form and saw a lot of postings that more than 8 caracters wil be ignored on trusted systems, but that is not the case because if i have a paswd of 9 the only 8 caracters wil not let me in....

Is there a fix for this?

You need to check the current size of the encrypted password for problem users. If the :u_pwd= entry has a string of 13 characters, then the password is only 8 characters or less. If the string is 24 characters, then the password is 9 or more characters. The 8 character problem has to do with using 10 character passwords on an unTrusted system where characters 9+ are silently ignored. On a Trusted system, every character is significant.

So if an unTrusted system is converted to Trusted, all characters entered for a password become significant and users that incorrectly type 9 or more on the old system will now be kicked out on the Trusted system. No problem though -- just change their password to what they want to use.

let me explain better:
I have a tcb entry.

i set the passwd qwer1234
I can login whit:
qwer1234
qwer12345
qwer123456
If i set the passwd on:
qwer1234567
I can login whit:
qwer1234567
but not whit
qwer123456
qwer12345678
so why if I use a 8 caracter passwd all the above is skiped, but If i use a 9 ore more carracter passwd only exact 9 ore more caracters are working?
program that I used to test this is su.

Hoi Freek,

are you running on 11.0 and if you are on 11.0, do you have patch PHCO_20334 installed?

All the same "problem" it looks like this is a design issue of hp....
