Hi, I’m a little confused by the above, in particular this part:

stderr: kinit: Keytab contains no suitable keys for krb\_gdc\_co\_test01@MSGREEN.DOM while getting initial credentials

This looks like krb\_gdc\_co\_test01@MSGREEN.DOM is being substituted where you have {{ krb\_hostname }} correctly.

Can you elaborate on where the problem is in your view?

Thanks!

Sorry for being dense, but these two values look the same to me:

krb\_gdc\_co\_test01  
krb\_gdc\_co\_test01

What part of that is the incorrect part?

Thanks!

Try {{ hostvars[inventory\_hostname][variable\_with\_variable\_name] }}
