Oddities with searching for a specific value of an attribute

[Sebastian Urbanneck <sebastian.urbanneck@uebergebuehr.de>]

Sorry for this weird topic, but I didn't know how to name this one.

These are the facts: we're using the phamm.schema from the PHAMM Project 
for saving virtual domain entries in our Ldap database. Searching for 
them is mostly no pronblem, but one specific circumstance is bothering 
me to death: when I try to search for a specific value of the attribute 
"vd", the corresponding entry is not always found. Any other attribute 
does the trick, but vd does'nt.

For example: the search for (using the root_dn)

ldapsearch -x -W -D "cn=admin,dc=uebergebuehr,dc=de" -b 
"ou=domains,dc=uebergebuehr,dc=de" "(vd=*) -s"one"

produces following output:
---------output-------------
# extended LDIF
#
# LDAPv3
# base <vd=lak-hessen.de,ou=domains,dc=uebergebuehr,dc=de> with scope 
baseObject
# filter: (vd=*)
# requesting: ALL
#

# lak-hessen.de, domains, uebergebuehr.de
dn: vd=lak-hessen.de,ou=domains,dc=uebergebuehr,dc=de
vd: lak-hessen.de

-------------------------------------

This is true for everytime I put a Wildcard (*) into the search pattern, 
and with scope "sub" there's also no matter in which part of the tree 
above this entry I am. But when I'm searching specificly for the value 
(lak-hessen.de) nothin is found, no matter in which entry I am and which 
scope use.

Strangely this pattern _is_ found when you go into the entry of the 
domain itself (vd=lak-hessen.de,ou=domains,...) and search with scobe 
'base'.

Any idea what I'm doing wrong? Or is this a bug? I think ACLs are ruled 
out because of using the root_dn.

I didn't want to file a Bug before being reallly sure that this is one
