More than 8 characters for passwd
Currently, the length of passwd is set to 8, which is the default.
I am to increase the length to more than 8. Please advise of the supported
options and steps.

In solaris (>8) you can use: increasing password length...
In HP-UX 11 and Tru64 you can enable TCB mode and get long passwords.
Linux, I believe it comes as standard.

I hope this helps.

It helps to know which OS you are using.

In AIX, for example (at least up to 5.3 TL8) the minimum length can be defined only up to eight characters. Anything after the eighth character is ignored.

Sorry, I am AIX 5.3 TL9. Can you change the password algorithm to have more than 8?

Hi.

I can only tell you what I know.

Here's an extract from the /etc/security/user file (albeit on TL8):

Code:
* minlen        Defines the minimum length of a password.  The default is 0.
*               Range: 0 to 8.
*
*   Note: The minimum length of a password is determined by minlen and/or
*         'minalpha + minother', whichever is greater.  'minalpha + minother'
*         should never be greater than 8.  If 'minalpha + minother' is greater
*         than 8, then minother is reduced to '8 - minalpha'.

Have a look at yours and see what it says.

(all assuming you are using the usual local user authentication)

What happens if you change password algorithm to smd5 or something that can give us more than 8 length? Is there anyone who has tried?

I'm going to take a wild guess and think 'smd5' is related to md5? Fundamental flaws in md5 have been exposed for a while now. You can generate md5 hash collisions on command.
