i just happened to notice that the following search(es) don't return the expected results:

>ldapsearch -xs base -b '' +
# extended LDIF
#
# LDAPv3
# base <> with scope baseObject
# filter: (objectclass=*)
# requesting: + 
#

# search result
search: 2
result: 0 Success

# numResponses: 1

>ldapsearch -xs base -b '' namingContexts
# extended LDIF
#
# LDAPv3
# base <> with scope baseObject
# filter: (objectclass=*)
# requesting: namingContexts 
#

# search result
search: 2
result: 0 Success

# numResponses: 1


below is the debug output from slapd for the first search - what am i doing wrong?

i'm using 2.4.21, courtesy of ubuntu.

thanks
