ldap auth problem

Hi,
I've just installed postgres 8.2.0-1 for win32 and wanted to try out the
built-in LDAP support(with Openldap and Novell eDirectory).
The following LDAP authentication was added to "pg_hba.conf" :

Openldap:
host all all 127.0.0.1/32 ldap
ldap://localhost/dc=dandoma,dc=cz;cn=;,dc=dandoma,dc=cz

However when trying to connect, it gave the error.
Look at the server log:
2006-12-31 19:34:59 LOG: LDAP login failed for user "cn=postgres
dc=dandoma
dc=cz" on server "localhost": error code 34
2006-12-31 19:34:59 FATAL: LDAP authentication failed for user "postgres"

eDirectory:
pg_hba.conf:
host all all 127.0.0.1/32 ldap
ldap://192.168.168.2/ou=win2000,o=plhb;cn=;,ou=win2000,o=plhb

Server log:
2006-12-29 13:50:18 LOG: LDAP login failed for user "cn=xxx
ou=win2000
o=plhb" on server "192.168.168.2": error code 32
2006-12-29 13:50:18 FATAL: LDAP authentication failed for user "xxx"

The problem seems to be in conversion of comma in suffix.

Thanks in advance.
