authconfig reporting (undefined method `[]' for nil:NilClass)

[dwashko]

I'm running into a problem running authconfig on chef 12. Without any attribute overrides in place via a role or databag the recipe fails with the following error:

moc-lx00010614 Running handlers:

If we put attribute overrides in place the error moves to a different line:

What appears to be the issue is line 54:

53 default['authconfig']['kerberos']['adminserver'] = 'kerberos.example.com'
54 default['authconfig']['kerberos']['passwdserver'] = node[:authconfig][:kerberos][:adminserver]

node[:authconfig][:kerberos][:adminserver] is not accessible and throws the error. Changing

 node[:authconfig][:kerberos][:adminserver]

to
default[:authconfig][:kerberos][:adminserver]

Resolves the issue.

I tried putting values in for both adminserver and passwdserver in the role but the error still occurs.

Chef server version 12
