RE: [uml-user] /etc/shadow problem

[Adil M. N. <ad...@hc...>]

The format of /etc/shadow file is
smithj:Ep6mckrOLChF.:10063:0:99999:7:::

each field in the shadow file is separated with ":" colon characters, and
first 2 field are as follows:
Username, up to 8 characters. Case-sensitive, usually all lowercase. A
direct match to the username in the /etc/passwd file.
Password, 13 character encrypted. A blank entry (eg. ::) indicates a
password is not required to log in (usually a bad idea), and a ``*'' entry
(eg. :*:) indicates the account has been disabled.

i have made the password field blank in the UML /etc/shadow file. now i
reboot the system and try to log in as root with blank password but it says
login incorrect
Also it is nt taking the old password as well. How to check the
pam-configuration?

Thanks and Best Regards, 
Adil Mujeeb

UML does not care about things like this ;-) How did you try to empty the
password field, with an editor, with 'vipw'? What do you mean with "doesnt 
update" - does /etc/shadow get changed or not? Are you sure your uml uses 
/etc/shadow? Check your pam-configuration. Try this (works at least on FC):

  passwd -d $USERNAME

If it works, check if it changed /etc/shadow or /etc/passwd.
