Max length of login name

[thewho?]

Hello,
N4000,11.0
Is there any way to increase the maximum length of a login name? Currently our system is 8 and would like to increase it. We'd like to avoid cross reference tables between win2k and hp.
Thanks,
Luis

Hi Luis,

You can go larger...BUT the better approach is to shorten the NT account names to 8.

Hi,

The user login name's length is limited to 8-bytes. Look at /usr/include/utmp.h or the man pages for utmp(4).

found some information in /usr/include/limits.h

/*
* The size of the storage required for a login name, in bytes,
* including the terminating null.
*/
# define _POSIX_LOGIN_NAME_MAX 9

/*
* Maximum Length of a login name.
*/
# define LOGIN_NAME_MAX 64

So general 8 chars is the maximum but HP-UX will recognize up to 63 chars.

I suppose a general consensus here would be to stick to a maximum of 8 char for compatibility purpose between open systems...

Luis,

Here's a good thread dealing w/pros & cons of using longer names as well as refs to some TKB docs.
