RE: programatically retrive the schema inforamation

["Matthieu Turpault" <matthieu.turpault@comelis.fr>]

Hello,

	I don't understand why your iPlanet server does not retrieve the correct information. Mine gives the following one:
%ldapsearch -x -h server.comelis.fr -p 389 -b "" -s base -LLL "(objectClass=*)" "+" "*"
dn:
objectclass: top
namingcontexts: o=foo
namingcontexts: o=NetscapeRoot
subschemasubentry: cn=schema

	Try the request 
		ldapsearch -x -h server.comelis.fr -p 389 -b "" -s base -LLL "(objectClass=*)" subschemasubentry

	Your server MUST (in the RFC sense) implement this functionnality.
	For more information about the rootDSE entry, see the URL http://www.techgalaxy.net/Docs/Dev/LDAPv3%20RootDSE%20Overview.htm
