Hi,

I want to configure openldap to work as a proxy for Active Directory. I have : A ldap database section to connect to active directory a dbd database to store local ldap A relay database to map Active Directory OU on a local OU This work fine but I have a problem with this type of filter : - ldapsearch -x -D "cn=manager,dc=openldap,dc=priv" -W "(&(objectClass=*)(whenChanged>=20080812000000.0Z))" - ldapsearch -x -D "cn=manager,dc=openldap,dc=priv" -W "(&(objectClass=*)(modifyTimestamp>=20080812000000.0Z))" => I have no result But with this type of filter : ldapsearch -x -D "cn=manager,dc=opencg21,dc=priv" -W "(&(objectClass=*)(uid=MyUsername))" => I can see the whenChanged and modifyTimestamp attributes. Can someone help me? I don't know how to have an error code to see where is the pb Thanks a lot. ---------------------------------------------- here is my slapd.conf --------------------------------------------
