Dear Gurus
i am unable to login in openweb mail as i have newly configure on Fedora Core 8 . i get my page but when enter username password it says access denied.
my configuration are..


[root@server etc]# vi /var/www/cgi-bin/openwebmail/etc/auth_unix.conf

# ***** IMPORTANT *****
#
# If you are going to use this option for check then the webmail on your
# Cobalt MUST be accessed via the the FQDN 'http://HOST.DOMAIN.COM'.
# Using 'http://DOMAIN.COM' will fail the user security check.

# change_smbpasswd
# -----------------------------------------------------------------------
# if this option is set to yes, openwebmail will also change the
# smbpasswd after changing the unix password successfully
set $unix_passwdfile_encrypted /etc/shadow
set $unixpasswdmkdb none
#passwdfile_plaintext /etc/passwd
#passwdfile_encrypted /etc/master.passwd
passwdfile_encrypted /etc/shadow
#passwdmkdb /usr/sbin/pwd_mkdb
passwdmkdb none
check_expire no
check_nologin no
#check_shell no
check_shell yes
check_cobaltuser no
change_smbpasswd no

Please tell me where is faul.

Secondly after updating any file what script i have to run to update the configuration..
