It may be that the basedn for autofs is just to find the maps. For keys 
it can use the value directly because they point to real entries.

Its good to know that this works, but we still need some way internally 
to detangle these and present the values in a way that it is easy to 
pick and choose.

I suppose one idea would be to create a new kind of map share, common. 
This would only allow ldap keys which could point to any valid key.

A common map could be added to any location.

I'm not sure how we'd represent this using compat though.
