Solaris

i am trying to create a user on solaris 10. it is not taking user name with more than ten characters. which file i need to edit to do this setting.

u can go through -

/usr/include/limits.h is listed in the man page for useradd but I am not sure if is it possible to chang that file.

Changing limits.h will only affect other commands if they are recompiled with that amended include file.

The best bet is to stick to 10 characters or less for the username and ensure the user's full name goes into the gecos field to enable searches on the user's full name, e.g.:

Code:

# getent passwd | grep "full name"

Did you check it doesn't ?

I did with Solaris Express (Solaris 10 should behave the same) and the OS accepts to create user accounts with quite long login names. Those with more than eight characters (not ten) will trigger a warning. The reason is these accounts names might be truncated or simply confuse some commands and/or other OSes. Other warnings will be triggered if the first character isn't alphabetic, if all characters are uppercase or if non alphanumeric characters are used.

That doesn't prevent the account to be created though. Moreover, Solaris accepts accounts stored in external LDAP directories which haven't such a limitation in login names.

ya i checked
it only give warning however user get created.
