Because you do not understand the term 'auxiliary'.

This means that you get all the rfc2307 attributes without needing to 
add the actual posix objectclasses.

Don't believe me???

use the Samba tool 'ldbedit' open sam.ldb, choose a user at random that 
doesn't have a 'uidNumber' attribute, add 'uidNumber: 20000' . Do not 
add anything else
Close and save ldbedit

Reopen ldbedit, go to the user you added the 'uidNumber' to, oh look it 
is still there, check the objectclasses, oh look, there isn't a posix 
objectclass!!
