[CentOS] Adding new automount entries to a map served via sssd from AD

I've been experimenting with setting up a CentOS 7 client using automount maps from Active Directory via sssd

I've followed the instructions given at:

https://ovalousek.wordpress.com/2015/08/03/autofs/

and all works fine

However, I can't seem to make the client 'see' new map entries added to the map on the AD server - I've tries reducing various timeout settings in /etc/sssd/sssd.conf to see if that helps - e.g.

entry_cache_timeout = 60 entry_cache_autofs_timeout = 15

but map entries don't appear at all - unless I run 'sss_cache -A' to invalidate the sssd autofs map caches

Does anyone know how to make new map entries appear automagically ?

Thanks
