Hi I read and used the article http://blog.wazollc.com/Lists/Posts/Post.aspx?ID=2 to authenticate my ad accounts when logging on to cent 5…however, once I edit the nsswitch.conf file, I can’t even log on as root or any local users anymore. Kinit seems to initialize fine doing a kinit username@xxxxxxxxxxxx <mailto:username@xxxxxxxxxxxx> , however doing a getent passwd adusername ….it just sits there in the shell and does nothing. I actually had to put all files back to where they were before the change to even be able to login locally or use sudo.I followed the steps line by line on this article but get stuck everytime….anyone has an idea or a better documented way of achieving what I am trying to do , please let me know.Thanks, Isaac
I'm using AD-via-Kerberos to authenticate users on several CentOS 5.1 systems. Setting it up was as easy as a single command line:
authconfig \
--usemd5 --useshadow --enablelocauthorize \
--enablekrb5 \
--krb5realm={AD Domain Name} \
--enablekrb5kdcdns --enablekrb5realmdns --update
This makes the necessary changes to /etc/krb5.conf, /etc/ and
/etc/nsswitch.conf. I am NOT using this for user information, just
password authentication, so I add user accounts for each authorized user.
You can also consider using the --disablesysnetauth flag, which disables authenticating "system" accounts via the network services and forces them to use local authorization. This should prevent entries in the AD for "root" and other system accounts from being used.
