Proxy to Active Directory: lost field

["Bogdan B. Rudas" <bogdan.rudas@nivalnetwork.com>]

Hello.

I use OpenLDAP as proxy for M$ AD.
The problem is: I can set filter only by some fileds like CN or Name.
I can't query AD by sAMAccountName via proxy 
Also I can't see many AD-specific fileds while browsing AD via OpenLDAP
proxy.


Request to proxy:

ldapsearch -M -LLL -H ldap://localhost:389 -x -D
"cn=aduser,ou=allusers,ou=itdep,dc=domain,dc=company,dc=com" -w
password -x -b "dc=domain,dc=company,dc=com"
'(sAMAccountName=bogdan.rudas)'  sAMAccountName

Return nothing.

Request directly to AD LDAP: 

ldapsearch -M -LLL -H ldap://ADserver.domain.company.com:1234 -x -D
"cn=aduser,ou=allusers,ou=itdep,dc=domain,dc=company,dc=com" -w
password -x -b "dc=domain,dc=company,dc=com"
'(sAMAccountName=bogdan.rudas)'  cn

Returns:

dn: CN=Bogdan Rudas.......skipped....
cn: Bogdan Rudas


Yet another request to proxy:

ldapsearch -M -LLL -H ldap://ADserver.domain.company.com:1234 -x -D
"cn=aduser,ou=allusers,ou=itdep,dc=domain,dc=company,dc=com" -w
password -x -b "dc=domain,dc=company,dc=com" '(name=Bogdan Rudas)'  cn
sAMAccountName

dn: cn=Bogdan Rudas.......skip.....
cn: Bogdan Rudas
SAMACCOUNTNAME: bogdan.rudas
