Hi, Am switching over from OpenLDAP to Fedora DS. The Java code that was creating user entries in OpenLDAP isn't working with Fedora DS and I thought perhaps the reason would be obvious to someone out there. This is what was working with OpenLDAP: dirContext = new InitialDirContext(anonymousEnv); // need to be administrator to do this dirContext.addToEnvironment(Context.SECURITY_PRINCIPAL, ADMIN_DN); dirContext.addToEnvironment(Context.SECURITY_CREDENTIALS,ADMIN_PWD); // ref: RFC 2798 // the inetOrgPerson represents people who are associated with an organization in some way. // mandatory attributes for inetOrgPerson are: cn, objectClass, sn Attribute ocAttr = new BasicAttribute("objectClass", "top"); ocAttr.add("person"); ocAttr.add("organizationalPerson"); ocAttr.add("inetOrgPerson"); // create the attribute set Attributes attrs = new BasicAttributes(true); // as LDAP attribute names are case-insensitive attrs.put(ocAttr); attrs.put("cn", username); attrs.put("sn", username); // not relevant but mandatory and can't put "" in there attrs.put("userPassword", password); attrs.put("uid", uid); // create entry in directory logger.debug("About to create subcontext: "+dn); accountContext = dirContext.createSubcontext(dn, attrs); Error I'm getting with Fedora DS at the last line of that code is: javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials] Have tried with ldapadd from the command line to create a user entry with all the same values and that works ok, so I'm a bit puzzled why the code doesn't work here. If anyone has any ideas, would appreciate them.
