I need to use OpenLDAP instead of OID (Oracle Internet Directory). I have the ldif file with all the users, groups and DIT from OID, but there are many attributes (like orclpassword orclisenabled ) that are not compatible with OpenLDAP, some of them were recognized adding the oracle schemas in the slapd.conf of OpenLDAP, but it's not enough. I'm triyng to add something like this... dn: cn=transmissions,cn=Users,dc=prueba,dc=com userpassword: ****** uid: transmisions sn: admon transmissions orclpassword: {x- orcldbpwd}1.0:A743481943433DAhg833 orclisenabled: ENABLED orclactivestartdate: 20051301000000c objectclass: inetorgperson objectclass: orcluser objectclass: organizationalperson objectclass: person objectclass: top But It throw me errors... ldapadd: Undefined attribute type (17) additional info: orclpassword: attribute type undefined Please, Could somebody give me an idea or information about how can I load an OID ldif file to OpenLDAP?
