We would like to know if there is a way to make AIX manage password longer than 8 characters.
Right now, AIX lets us use passwords longer than 8, but it will only store the 8 first characters.

Does anyone know if this can be done?

Thanks

This case was raised few weeks ago and the answer was that up to AIX5.2 you can't exceed 8 character in the password! You can do that only in AIX5.3.

I can't find the previous post! Once i find it i will post it here for your reference.

Khalid

I've done a search in the forum, but I've not seen this post.
Our servers have AIX 5.3 TL04, so I suppose it can be done.
There is also a weird thing. We have put in /etc/security/user that passwords must have at least 3 non-alphabetic characters and a min length of 8. In all our servers except one, if you put a password like qwerty123 it lets you, but AIX will only store as password qwerty12 (less than 3 non-alphabetical), but in one server this will fail, it won't let you put a password if it doesn't have the 3 non-alphabetical in the 8 first characters.

To set the maxnumber of characters for 5.3
chdev -l sys0 -a max_logname=9

As for the min length and the non-alphabetic characterr...do the individual user stanza reflect the difference that you are experiencing?

Tried chev -l sys0 -a max_logname=10 and it didn't work, max password length is still 8 (if I put a 10 characters password, it only stores the 8 first).
What this does is to increase the max length of the user's name, not the password length.

Thanks anyway

logname is lenght of user name not password. Those solutions are bad. I will look into base to find if there is possibility for longer password.

Well, I'm going to take a look at it, and I'll try it on a test server, but I don't know when will this be.
Anyway I'll let you know.
