Top Forums UNIX for Beginners Questions & Answers Unable to create new user without lower character
# 8  
Old 06-23-2017
I've not had an issue with all capital letter users either, except on the console. There I would fail a login using any random lower-case characters and then you can login with the one you want.

I ran AIX, Solaris (2.5 to v8), HP-UX 11.11, Dynix 4 and RHEL 5 & 6 quite happily like this. Our application required all capitals because it was originally grown on an IBM mainframe running VM/XA & MVS/ESA (gosh I'm old! Smilie) and they assumed every user account was only capitals.



Login over the network seemed never to be a problem. Are we worried about users defined in LDAP / AD perhaps etc.? We'd gone away from user login to the server by that point so they logged in to the application instead.

usermgmt.conf

USERMGMT.CONF(5)					      BSD File Formats Manual						  USERMGMT.CONF(5)

NAME

     usermgmt.conf -- user management tools configuration file

SYNOPSIS

     usermgmt.conf

DESCRIPTION

     The usermgmt.conf file defines the default values used by the user management tools, useradd(8) and friends.

     Options in this file can be set by manually editing /etc/usermgmt.conf or using the -D option to useradd(8).

     base_dir	sets the base directory name, in which new users' home directories are created when using the -m option to useradd(8).

     class	sets the default login class for new users.  See login.conf(5) for more information on user login classes.

     expire	sets the default time at which the current password expires.  This can be used to implement password aging.  Both the expire and
		inactive fields should be entered in the form ``month day year'', where month is the month name (the first three characters are
		sufficient), day is the day of the month, and year is the year.  Time in seconds since the epoch (UTC) is also valid.  A value of
		0 can be used to disable this feature.

     group	sets the default primary group for new users.  If this is '=uid', then a uid and gid will be picked which are both unique and the
		same, and a line will be added to /etc/group to describe the new group.  It has the format:
		      group gid | name | =uid

     homeperm	sets the default permissions of the newly created home directory if -m is given to useradd(8).	The permission is specified as an
		octal number, with or without a leading zero.

     inactive	sets the default time at which new accounts expire.  A value of 0 can be used to disable this feature.	Also see the expire field.

     password	specifies an already-encrypted default password.

     preserve	If this value is one of 'true', 'yes', or a non-zero number, then the user login information will be preserved when removing a
		user with userdel(8).

     range	specifies the uid boundaries for new users.  If unspecified, the default is ``1000..60000''.  It has the format:
		      range starting-uid..ending-uid

     gid_range	specifies the gid boundaries for new groups.  If unspecified, the default is ``1000..60000''.  It has the format:
		      gid_range starting-gid..ending-gid

     shell	sets the default login shell for new users.

     skel_dir	sets the default skeleton directory in which to find files with which to populate the new user's home directory.

FILES

     /etc/usermgmt.conf
     /etc/skel/*
     /etc/login.conf

SEE ALSO

     login.conf(5), passwd(5), user(8), useradd(8), userdel(8), usermod(8)

HISTORY

     The usermgmt.conf configuration file first appeared in NetBSD 1.5.
