Have you tried to manually add the user, adding to the passwd file, and so on?

i have added manually to /ec/passwd file

example: test1.test:x:555:555::/home/test1.test:/bin/bash

and when i am trying to change the passwd using passwd test1.test
i am getting fallowing message

passwd test1.test
Changing password for user test1.test.
passwd: Authentication token manipulation error

and when i manually set the passwd in place of x in passwd file
there is happening a authentication failure. when see to login to system with that username and passwd its telling passwd is incorrect.

i have the same probleme with useradd, but manually adding the user works with fedora core 1

Is there a reason for useradd not to accept dot's in a username?

Or is it a tiny bug?

best regards,

PS: @ hanu: u also have to edit /etc/shadow and maybe create a proper group in /etc/group and /etc/gshadow

hi struberg

i tried like that adding to /etc/shadow file . but it dint work in redhatlinux 9 intel based . so what i did is i have created entries in /etc/aliases file like for test.test: test.test
so what ever mails come for test.test will move to test_test
also i have config all our outlook express with test_test nad passwds with displaying name as test.test

i have few users only so i am not fasing any problems now.
