(ITS#7252) Referral Problem with SQL Backend

regarding my mail to the mailinglist:

I'm using openldap with SQL-Backend (Postgres). The configured referral on this
server behaves not the way it should. The bind dn of the referral is overwritten
by the bind dn (of ldapsearch).

Following are the configuration and the Log files of the LDAP Server with SQL
Backend at Loglevel -1. In the Logfile you can see the starting of the server +
the search ?ldapsearch -xLLL -h localhost:389 -b dc=sselab,dc=de?. I think at
line 4114 one can see how the referral is used.

To demonstrate the behavior:


Search for the referral Object:

     user@user-desktop:~$ ldapsearch -M -xLLL -h localhost:389
"(objectClass=referral)" '*' ref

     dn: dc=tim,dc=sselab,dc=de

     objectClass: referral

     objectClass: extensibleObject

     dc: tim

     ref: ldap://localhost:390/dc=tim,dc=sselab,dc=de#


which is exactly what I want!


But searching all objects:

     user@user-desktop:~$ ldapsearch -xLLL -h localhost:389 -b dc=sselab,dc=de

     dn: dc=sselab,dc=de

     objectClass: dcObject

     dc: sselab




     # refldap://localhost:390/dc=sselab,dc=de??sub


Results with the wrong dn in refldap!


Search with the dc=tim DN :

     user@user-desktop:~$ ldapsearch -xLLL -h localhost:389 -b

     Referral (10)

     Referral: ldap://localhost:390/dc=tim,dc=sselab,dc=de??sub


If you need more Information please let me know.
