[CentOS] SSSD and auto.master

Hi,

I have successfully configured autofs to use SSSD, which in turn retrieves 
information from an Active Directory.

/etc/nsswitch.conf is set to check 'files sss' and I'd be really grateful if 
someone could confirm that I have configured my auto.master in a sensible way 
- it basically calls other auto.masters from AD.

/etc/auto.master looks like this:

* * *

# Default stuff
/misc	/etc/auto.misc
/net	-hosts

# Records in Active Directory
+auto.master-fsa
+auto.master-fsb

* * *

I ask because I have replicated my config on another similar server and SSSD 
logs report there are no maps which is a little odd.

Thanks
