This all started because at the time, a large number of users trying out
the then-new samba3upgrade (now samba-tool domain classicupgrade) code
had it fail, because Samba built without ldap headers. Nothing at build
time warned them (or warned them clearly enough) that they were missing
The same happened with ACLs, getting to the point that I had to add a
clear test to the provision stage to give a clear 'you didn't build with
ACL headers' error. (For smbd file server users, it is even less clear,
as there are no errors, just less features).
The users would eventually rebuild, but felt that configure should have
made it harder to proceed to build something less than 'the complete
It hasn't come up as much recently, as we changed the list of packages

think we should encourage a situation where users have to explicitly
choose to build without these important features.
