Er, no, you are stuck with the above on an existing Unix
domain member, but on new Unix domain members I would use this:
idmap config * : backend = tdb
idmap config * : range = 3000-7999
idmap config SAMDOM : backend = rid
idmap config SAMDOM : range = 10000-80000
The '*' domain is for the 'Well Know SIDs' and anything outside of the
'SAMDOM' domain and there are less than 200 'Well Known SIDs', so 4999
ID's should be more than enough.
When it comes to the 'SAMDOM' domain, if you do reach the user ID
'80001', this wouldn't be a problem with my suggested lines, just
change the '80000' to '90000'. If the '*' domain is above the 'SAMDOM'
domain, then you are limited to the difference between the high number
for the 'SAMDOM' range and the low number for the '*' range. In your
case '40000' and '50001', for most people this might not be a problem,
but for some, it would be a big problem.
