Due to circumstances beyond my control, we are setting up some users on an
IBM RS/6000 with userids that are ALL UPPERCASE. These users are migrating
from MVS and we are trying to make the transition as painless as possible.
However, when I log in to one of these accounts I get a nasty message from
the login program about turning off my caps lock. We are connecting to
the box with KI Research LAT. As far as I know it just runs the login program
I've logged in to other flavors of Unix and I don't get this message. I can
log in OK but I would prefer not to get "yelled" at.
All suggestions welcome.

AIX is a case sensitive operating system, whereas MVS and VM are case insensitive. With VM it doesn't matter if you enter "COPY All NoteBook A OLD NOTEBOOK A", but with AIX there is a difference between "All.Notebook" and "all.notebook" and so on. The commands are all lower case characters; your users will have to either shift to lowercase once they login, or tolerate upper case characters only on their screen. >However, when I log in to one of these accounts I get a nasty message from >the login program about turning off my caps lock. We are connecting to >the box with KI Research LAT. As far as I know it just runs the login program It is the login program. The AIX login program has code which makes the assumption that any user logging in with all upper case letters is not able to enter lower case letters, therefore the user ID is case-shifted downward, and the tty modes are set so that upper case letters are converted to lower case letters on input, and lower case letters on output are converted to upper case letters. >I've logged in to other flavors of Unix and I don't get this message. I can >log in OK but I would prefer not to get "yelled" at. This is actually done on quite a few versions of UNIX. To try this out, enter your user name IN ALL CAPS. YOU SHOULD BE PROMPTED FOR "USER'S \PASSWORD: ". The \P is an uppercase P, with ASSWORD being in "lower" case. The case translation has been done on every version of UNIX I've used since 1981. It actually dates back into the 70's when there were 6 bit terminals that didn't support lower case. [ Disclaimer: I speak only for myself.
