SSH or su command breaks because of long username (more than 16 chars)

[gcl]

Our nas integrated woth our LDAP or Active Directory and we use the following format "domain\usernameXX" .
it won't work when they are longer than 16 characters. (which is FreeBsd default).
I believe it can be set up to 64 chars.

Thanks.

This is known AFAIK, its a limitation on FreeBSD utmp. I think FreeBSD 9.0 fixes this with utmpx...

Violating standards will hurt. One such standard is length of userid.
To be future-safe, limit userid to < 12 chars, usacii character set.

Our nas use LDAP or Active Directory for authenication.. that is why it longer than 16 chars. FreeBSD kernel support longer than 16 chars.

And thats why you have problems.
Even if you could tweak freenas you will encounter other problems later.

Userid <= 8 bytes usascii will be a safe bet. ( backslash will never be a safe bet enywhere )
