Author: tridge Date: 2005-10-14 07:38:16 +0000 (Fri, 14 Oct 2005) New Revision: 10990
WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=10990 Log: the beginnings of a program designed to work out the minimal schema needed to represent all the current records on a ADS LDAP server. The idea is we will use something based on this code to work out exactly what schema elements we will need for our initial ADS schema. I plan on expanding this code to automatically work out attribute properties, and write out a schema file that we can load into ldb. Interestingly, it looks like we only need 43 objectclasses and around 200 attributes to represent all records of a newly installed w2k3 ADS server.
