w2kusers.deny

w2kusers.deny(4)					     Kernel Interfaces Manual						  w2kusers.deny(4)

NAME

       w2kusers.deny - Authentication file for Windows 2000 Single Sign On.

SYNOPSIS

       # Comment account_name

DESCRIPTION

       The  w2kusers.deny is a text file containing a list of user account names.  When an account is included in this file, the Windows 2000 Sin-
       gle Sign-On software verifies only the UNIX authentication for the named account.

       To add user accounts to the file, use a text editor to enter the user's UNIX  account  name.  The  following  syntax  rules  apply  to  the
       w2kusers.deny  file:  Only  one	user  name can be entered on a line.  The user name must exactly match a user name in the UNIX /etc/passwd
       file.  Comment lines begin with a pound sign (#).

EXAMPLES

       The following example shows a typical w2kusers.deny file: # The following file lists account names that are not allowed to use #  the  Win-
       dows  2000  authentication  information	when it is enabled.  # Account names must match exactly the user account name in the # /etc/passwd
       file.  # # Syntax: account_1 #		 .  #		 .  #		 .  #	      account_n # root	nobody	nobodyV  daemon  bin  uucp
       uucpa auth cron lp tcb adm ris wnn pop imap Peter Dave Beth Martha
