LDAP Adding entries to the server directory :: how to ?

From looking at the code, I have questions about the following line:

String MGR_DN = "dc=monarch,dc=com";

This does not look to be a good distinguishedName (dn) for an account. I would expect this to be something more like "cn=manager".

Try using the account you set up as the administrator / manager of the directory.

The following may cause you issues as well:

String dn = "uid=ac" ;

I think this should probably be something like
String dn = "uid=ac,dc=monarch,dc=com" ;
or
String dn = "uid=ac,ou=users,dc=monarch,dc=com" ;
the dn should represent the full path to this user object. This path has to include the container where the user object will reside.

The second example dn above uses an imaginary organizationalUnit (ou) - I do not know what, if any ou's exist in your directory - and the domainComponent (dc) that contains the ou.

Also check to see how the directory set up - it may want the commonName (cn) to be part of the dn instead of uid.

And, I think you may be missing a mandatory attribute for the new user object - cn - this is usually a combination of the first and last names and can be part of the dn.

After looking at the Sun LDAPEntry (http://docs.sun.com/source/816-5618-10/netscape/ldap/LDAPEntry.html) web page, I think that the dn for the new LDAPEntry should be the full dn not an rdn - I think that is how the object is found.

From the Sun LDAPConnection (http://docs.sun.com/source/816-5618-10/netscape/ldap/LDAPConnection.html) web page:

add

public void add(LDAPEntry entry)
throws LDAPException

Adds an entry to the directory.

Before using this method, you need to create an LDAPEntry object and use it to specify the distinguished name and attributes of the new entry. Make sure to specify values for all required attributes in the entry. If all required attributes are not specified and the LDAP server checks the entry against the schema, an LDAPException may be thrown (where the LDAP result code is OBJECT_CLASS_VIOLATION).

For example, the following section of code creates an LDAPEntry object for a new entry and uses the object to add the new entry to the directory. Because the definition of the LDAP inetOrgPerson class specifies that the cn, sn, and objectclass attributes are required, these attributes are specified as part of the new entry. (mail is not required but is shown here as an example of specifying additional attributes.)

Here is a good example of creating a user in LDAP using java from LDAP GURU (http://www.ldapguru.com/modules/newbb/viewtopic.php?topic_id=1999&forum=6&post_id=6017)

public class Add
{
public static void main( String[] args )
{
/* Specify the DN we're adding */
String dn = "uid=wbjensen, ou=People, o=Airius.com";

/* Specify the attributes of the entry */
String objectclass_values[] = { "top",
"person",
"organizationalPerson",
"inetOrgPerson" };
String cn_values[] = { "William B Jensen",
"William Jensen",
"Bill Jensen" };
String sn_values[] = { "Jensen" };
String givenname_values[] = { "William", "Bill" };
String telephonenumber_values[] = { "+1 415 555 1212" };

LDAPAttributeSet attrs = new LDAPAttributeSet();
LDAPAttribute attr = new LDAPAttribute( "objectclass" );
for( int i = 0; i < objectclass_values.length; i++ )
{
attr.addValue( objectclass_values[i] );
}
attrs.add( attr );

attr = new LDAPAttribute( "cn" );
for( int i = 0; i < cn_values.length; i++ )
{
attr.addValue( cn_values[i] );
}
attrs.add( attr );

attr = new LDAPAttribute( "sn" );
for( int i = 0; i < sn_values.length; i++ )
{
attr.addValue( sn_values[i] );
}
attrs.add( attr );

attr = new LDAPAttribute( "givenname" );
for( int i = 0; i < givenname_values.length; i++ )
{
attr.addValue( givenname_values[i] );
}
attrs.add( attr );

attr = new LDAPAttribute( "telephonenumber" );
for( int i = 0; i < telephonenumber_values.length; i++ )
{
attr.addValue( telephonenumber_values[i] );
}
attrs.add( attr );
attrs.add( new LDAPAttribute( "uid", "wbjensen" ) );

/* Create an entry with this DN and these attributes */
LDAPEntry myEntry = new LDAPEntry( dn, attrs );

LDAPConnection ld = null;
int status = -1;

try
{
ld = new LDAPConnection();
/* Connect to server */
String MY_HOST = "localhost";
int MY_PORT = 389;
ld.connect( MY_HOST, MY_PORT );

/* Authenticate to the server as directory manager */
String MGR_DN = "cn=Directory Manager";
String MGR_PW = "bigDaddyPassword";
ld.authenticate( MGR_DN, MGR_PW );

/* Now add the entry to the directory */
ld.add( myEntry );
System.out.println( "Entry added" );
}
catch( LDAPException e )
{
if ( e.getLDAPResultCode() == LDAPException.ENTRY_ALREADY_EXISTS )
System.out.println( "Error: Entry already present" );
else
System.out.println( "Error: " + e.toString() );
}

/* Done, so disconnect */
if ( (ld != null) && ld.isConnected() )
{
try
{
ld.disconnect();
}
catch ( LDAPException e )
{
System.out.println( "Error: " + e.toString() );
}
}

System.exit(status);
}
}

To sum it up, I believe you need to specify the dn of the new user when you create the LDAPEntry object.

then the dn should have entry like
"uid=ac,ou=cygnet,dc=monarch,dc=com"

Hello

I am able to connect to the ldap server by calling the Add.java class into any .java class and it connects successfully but the entry is not added
The code for the Add.java is being checked standalone also only it does not run with the servlet.

But when i call the same code within the servlet it does not show the result
The log file within the container od the servlet shows

LDAPException not found in doPost() method

Here is my servlet code

package com.chat.java;

Hello
Thanks for the reply. Now I am able to make entries to the LDAP server via the Add.java class but not throuh the servlet it runs as a standalone
When integarted with the servlet the code does not do any entry

Even it does not connect to the server . I am using the Netscape sdk for java so is it i need to include all the classes of the sdk in the container of the servlet.do i need to include the .jars to the root of the container

And one more thing that if I only want to make the entry of the user as
.......uid , company name and organization unit

which object class should i include in the Adder.java class .As i have included the code in the 1st post of mine tell me what modifications are required

regards
Jignesh

Hello
I have ran the whole code to add the entries standalone and the entries are added

But when i did it using servlet the servlet does not execute any line of the code even no print statement I could see on the console of the web server
I suppose the whole code is being bypassed coz theres no error in the log file

Plz help
Jignesh

Hello Sir
I am not getting any error regarding the Add.java class not found but the classes that are being extended as a part of the Add.java class
(LDAPEntry,LDAPAttribute,LDAPAttributeSet,LDAPConnection) are not being reached by the code in the servlet even when i have included the classes of LDAP into the servlet container

What shall be the error
Plz help coz its urgent

Thanks
Regards
Jignesh
