Able to login in CAPS

[PROSANJIT MALLICK]

Hi everybody,

I am facing a peculiar problem in hp-unix.
I am able to login even if I use CAPS ON. This is only happening from terminals directly connected to Server
i.e MUX and Terminal Servers.
Through telnet it is giving me error as expected.

Can anybody help me out ?

Bye
Prosanjit

Hi Prosanjit:

This is normal behavior. 'getty' performs the following ahead of calling 'login' (from the 'getty (1M)' man page:

The user's name is scanned to see if it contains any lowercase alphabetic characters; if not, and if the name is non-empty, the system is told to map any future uppercase characters into the corresponding lowercase characters.

This goes back to the days of old TTY terminals (that were only all uppercase), so Un*x would assume that an all uppercase login name needs to be lowercase (since Un*x works mostly lowercase).

The work around is to enter any lowercase letter on the first login, press return on password prompt (let it say bad user/password), then on the second login prompt, you can enter in your all uppercase login ID.
