Hello Rich,
Thank you again for your support.
With your direction, I have found the code sample in extracting LDAPSchema
out of an LDAPConnection. From the LDAPSchema, extract LDAPObjectClassSchema
then add a new LDAPAttributeSchema to the LDAPSchema.
However, when I tried out this sample to the Aphelion Directory Server that
I worked on it failed at the fetchSchema method. Returned exception message
is "No such object".
LDAPConnection ldapConn = new LDAPConnection();
// Construct a new LDAPSchema object to get the schema.
LDAPSchema dirSchema = new LDAPSchema();
try {
// Connect to the server.
ldapConn.connect(LDAP_HOST, LDAP_PORT);
// Get the schema from the directory.
dirSchema.fetchSchema(ldapConn);
// Get and print the inetOrgPerson object class description.
LDAPObjectClassSchema objClass =
dirSchema.getObjectClass("inetOrgPerson");
if (objClass != null) {
System.out.println("inetOrgPerson := " +
objClass.toString());
}
// Get and print the definition of the userPassword attribute.
LDAPAttributeSchema attrType =
dirSchema.getAttribute("userpassword");
if (attrType != null) {
System.out.println("userPassword := " +
attrType.toString());
}
Does this means the Aphelion Directory Server does not support extracting
schema over LDAP protocol?
