LDAP JNDI Tomcat 6 Realm

I am trying to use a JNDIRealm in Tomcat 6 to connect to an active directory server. My server.xml realm tag looks like:
<Realm className="org.apache.catalina.realm.JNDIRealm" connectionName="CN=M123456,OU=Users,OU=NNN,DC=nnnn,DC=nnnnnn,DC=org" connectionPassword="xxxxxxxx" connectionURL="ldap://xxxxxx.xxxxxxxx.xxx:389" userPattern="CN={0}, OU=Users, OU=NNN, DC=nnnn, DC=nnnnn, DC=org" />
When I test my application on my local server, my user name and password don't work. I get no error messages in my local server console. Any ideas on how to debug or correct?
My LDAP information looks like (with selected values shown after "->" symbol):
cn=M123456, OU=NNN, DC=nnnn, DC=nnnnnn, dc=org
homeMDB

Hi All,
I've worked out the problem... It was all to do with Vista / Windows 2008 TCP Auto-Tuning. See this article.

JSF - Tomcats Realm - General Question

Hi @ ll,
I've written a wep app in JSF.
Evererything works fine. Also the autentification by Tomcats JDBC Realm.
My problem is. only the login is not written in JSF, cause every form get id prefix.
I know its "normal" in in JSF.
But Tomcat expect a submit "j_security_check" without a prifix like "_id0:".
I don't know to figure it out.
I've had a look into the Jaas dokumentation. It will take some hours/days to lean it.
And I think Jaas is overdosed for my very simple webapp.
Now my general Questen:
Is it posible to write a simple form based login in Java Server Pages to use Tomcats Realm?
Is there a simple alternative to Jaas?
THX 4 your advise.
esion

It's not possible with the default set of components.
That said, there may be a component set that provides a form-based authentication component, but off the top of my head I'm no aware of one.
It wouldn't be that difficult to roll your own either.

LDAP JNDI bootstrap info at each cluster node

Any suggestions on the best way to distribute LDAP JNDI bootstrap
          information (host:port/DN/pwd/searchbase) to each node in the cluster? I've
          thought of deploying individual bootstrap files, but then I'd have to
          encrypt them and I don't like the idea of these files authentication files
          laying around on (potentially) distributed hosts. Clustered EJBs could use
          an abstraction layer that hides this stuff from them, but the abstraction
          layer needs the bootstrap info before accessing LDAP through JNDI.
          I feel like there's some simple, elegant manner of doing this, but I'm
          missing it because my head is full of LDAP searchbases and filter syntax....

URGENT HELP NEEDED ... Tomcat Realm and JRE1.4 plug-in problem

I have tried the Security Realm of Tomcat. Since I do not have
an LDAP server, I decided to use the Tomcat-users.xml file in
Tomcat\conf directory.
I added the following lines of code in the web.xml file.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>

<role-name>webviewer</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
The <role-name> "webviewer" is added into "Tomcat-Users.xml" as the following:
<tomcat-users>
<user name="test" password="password" roles="webviewer" />
</tomcat-users>
So, now when we type the url: http://localhost:8080/adbpdbre/default.htm, TOMCAT shows a dialog box asking for UserName: and Password:Now, only when we give the username and password, it shows the page. This is exactly what we want.
But the problem now is, this default.htm page, has 5 links to 5 applets. The first time that I click on one of these links, the JRE plug of 1.4 shows a dialog again asking for the username and password. Till I dont provide the username and password the system doesnt go ahead and applet doesnt load. I do not want the JRE to ask me for the username/passwords again..How to avoid this ?
Can you give me some more information on this. Ultimately in the production usage, we will be using LDAP and not Tomcat's memory realm.
URGENT HELP NEEDED ... I need to get back to my client on this.
Help would be v. much appreciated.

In the config file, you 're essentially saying that you want Tomcat to prompt for usr/passw on every request (url-pattern = /*) made by a 'webviewer', and that's exactly what Tomcat is doing.
Consider using specific url-patterns & roles for resources to be protected. If for now, all you need is to protect the first page, use a more specific url-pattern.
Just an advice : if you'll be using LDAP in production, do not waste time with Tomcat's Security Realm and the BASIC authentication type, since the two have not much in common. Start reading doc on LDAP, and code a prototype, or even better, a vertical slice of the app (i.e a proof of concept).

now I have a problem , when I use the authenticate method, I use a invalid username which should triger an exception when binding, if the passoword is null , there are no expections and the authenticate would return true on invalid username.
Those codes is ok in IBM WeBsphere.
Who can help me ?
please and thanks.

Access to a Tomcat Realm

HI! I am trying to get the following code to run, but I still get a nullpointer exception.
This code is in a servlets init method, and should be loaded on tomcats startup.
Server server = ServerFactory.getServer();
//Note, this assumes the Container is "Catalina"
Service service = server.findService("Catalina");
Engine engine = (Engine) service.getContainer();
Host host = (Host) engine.findChild(engine.getDefaultHost());
//Note, this assumes your context is "myContext"
Context context = (Context) host.findChild("myContext");
Realm realm = context.getRealm();I've set the privileged parameter in the webapp/webcontent/meta-inf/context.xml file.
Why I could'nt access this classes?? Where is my misstake?
Thank you for your answer!

Yeah, it looks like we may have to alter the client code to basically pass their login via a "form"....but we'd rather not do that.
BTW, this is a SOAP server we'll building...so not only would it been a real pain to alter the client's XML output (and therefore our corresponding remote method), but the login data would be even more in plain view.

How can I use LDAP for Tomcat authentication ?

Hi
I have an implementation of apache 1.3.20 with tomcat 3.2.3. I an doing
auth. with a ldap server wihich works prefectly with apache
mod_auth_ldap (module). When i am trying to read the environment
variables with a cgi , REMOTE_USER returns me the authentificated user
but when i am doing a getremoteuser() in my servlet with tomcat , it
returns NULL Why ?
I came accross this page when looking for material and
http://www.peacetech.com/java/files/apache/tomcat/
did the following
1) Downloaded - jndi_auth_beta1.jar, Extracted jndi_auth.jar file which contained
class files and plcaed them inside my tomcat/lib directory
2) Then i have updated the server.xml file of my Tomcat, that i wanted to use LDAPRealm
<RequestInterceptor className="com.peacetech.webtools.tomcat.LdapRealm"
debug="1"
directoryUrl = "ldap://csee.usf.edu:389"
searchBaseContext = "o=usf.edu"
searchFilter = "uid={0}"
searchScopeAsString = "sub"
securityAttributes = "securityEquals"
attributesReadByOwner = "true"
connectionMaxPoolSize = "10"
ldapVersion = "3" />
Then i had shutdown and restarted the server after some initial hickups, then i have tried to open some sample JSP and sevlets in the examples directory of my server. But i was not asked for any UserId/Password. Was wondering if i have done anything wrong ??
Thanks

Maybe you should look at JAAS for that. I think it could help you.

Using LDAP as security realm

Hi,
Our goal is to use LDAP(Iplanet Directory Server 5.0) as a security Realm
for Weblogic Personalization and Commerce 3.5.
Using the WLCS console, I've modified the config.xml file and following
elements are added:
<LDAPRealm AuthProtocol='simple' Credential='admin'
GroupDN='ou=groups,dc=netnumina,dc=com' GroupIsContext='false'
GroupUsernameAttribute='uniquemember'
LDAPURL='ldap://sanand.netnumina.com:389' Name='wlcsLDAPRealm'
Principal='uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot'
UserAuthentication='local' UserDN='ou=people,dc=netnumina,dc=com'
UserNameAttribute='uid'/>
<CachingRealm BasicRealm='wlcsLDAPRealm' CacheCaseSensitive='true'
Name='wlcsCachingRealm'/>
But when we try to restart the WLCS, it throws java exceptions that context
is not initialized and I get the following error
<Jun 15, 2001 3:41:28 PM EDT> <Emergency> <Server> <Unable to initialize the

Does anyone has any experience using anything other than the default Realm?

I'm not sure, but I suspect you can't
since this would create a circular dependency -
your realm would rely on the upper level security
checking calls but those calls would rely on your
realm.
My suggestion is to give it a try and see what
happens.

Is it possible to use weblogic.security.acl.Security with my custom

LDAP JNDI Error

Hi all,
I am trying to just print out fields from JNDI Module Groups which are inside Active Directory. The following is the code I use:-
for each ad in User
do
logMessage "Entered User Name IF loop"
logMessage " User Name =====: " + ad.givenName
logMessage" User Name =====: " + ad.uid
logMessage " User Name =====: " + ad.userPrincipalName
//requestedByLastName = ad.givenName
end
I get the following error:-
The method 'Person' from class 'Person_Details.Default_1_0.Instance' could not be successfully executed.
Caused by: [LDAP: error code 4 - Sizelimit Exceeded]
Could anyone please let me know what exactly is this error because I am doing nothing but printing out values from the AD to ALBPM logMessages..

Aaaarrgghhhh....
In your code you have
// Get all the attributes of named object
Attributes answer = ctx.getAttributes( "cn=*anna*");If you are just retrieving an object rather than performing a search, you need to use the full distinguished name which means it will be something like:
Attributes answer = ctx.getAttributes( "cn=Anna,ou=People,dc=osu,dc=edu");And if you ever get around to writing code that performs a search, DO NOT use a search filter of the form:
"cn=*Anna*"as your query ends up just being a stupid wild card query and will probably not be able to take advantage of any indexes that are present on the DIT.
You queries will time out and you network admins will become quite angry.

LDAP & JNDI

I'm using the following text in my dn entry while trying to access an LDAP server:
oEnv.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
oEnv.put(javax.naming.Context.PROVIDER_URL, m_sProviderUrl);
oEnv.put(javax.naming.Context.SECURITY_AUTHENTICATION, "simple");
oEnv.put(javax.naming.Context.SECURITY_PRINCIPAL, "uid=user1,dc=domain,dc=com");
oEnv.put(javax.naming.Context.SECURITY_CREDENTIALS, sPassword);
This does not work... But if I change the "uid" with "cn":
(javax.naming.Context.SECURITY_PRINCIPAL, "cn=First Last,dc=domain,dc=com");
I can access the LDAP server, and the authorization is successful.. Any idea why is that?
Am I doing something wrong in accessing the LDAP server? Or is there something not configured correctly on my LDAP server??

beavis,
If you just want to authenticate the user maybe you could lookup the user's cn first(by using any already authenticated user whose cn is known), then authenticate again using the cn of the user to compose a distinguished name.
I use kerberos to authenticate with the AD and the user's Windows login id would be used instead.....
I use the following code to search for a particular user instead of looping around....
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://company.com");
env.put(Context.SECURITY_AUTHENTICATION, "GSSAPI");
try
DirContext ctx = new InitialDirContext(env);
* user login id "userid" for searching
String filterString = "sAMAccountName=" + userid;
* specify your interested attributes for the return user
String[] returnAttr = { "cn", "sAMAccountName" };
StringBuffer filterBuffer = new StringBuffer(filterString);
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(returnAttr);
ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);
* userSearchBase is the distinguished name of the starting OU from where your
* user will be searched.
* e.g. "ou=People, dc=company, dc=com"
NamingEnumeration results = ctx.search(userSearchBase, filterString, ctls);
if ( results != null && results.hasMore() )
Wish that could be helpful....

I think mysql jdbc library should add to the class library path of your project.

JNDI: Tomcat 5.0 Pulling My HAIR OUT!

The commented out portion works fine, this just kinda was my way of knowing the MySql Driver is working fine and in the correct location. Any ideas PLEASE? :) Thanks!!

Hi Shawn,
I am going crazy for last 15 days , but not found a solution . I called godaddy people , but no perfect answer . After looking at this thread I got my hopes back . Hopefully you read this message and will reply back.
I am using godaddy Linux hosting shared environment unlimited with java support .
I am able to connect to database directly through my JSP or servlet and able to get the result . I mean if I hard code the database connection string,userid and password . But if I use context.xml I am getting null pointer exception on the screen . As per the tomcat configuration install doc if you copy context.xml under META-INF/context.xml It will be picked by tomcat and writes it under conf\Catalina\localhost directory with your jar file name . In shared environment I am not getting a away to check this ..
Is there any way to check the file copied properly or not to conf\Catalina\localhost directory?
Or if it doesn't there any other way to implement connection pooling in Godaddy environment?
and surprisingly the logs what they are asking me to check are under stats directory with error_logs directory . But that doesn't contain much information.Are there any other error logs I can check?
You mentioned in the above message you were able to check the shared libraries they are hosting. How do I check it?
Sorry for too many questions , But I am desperate .
Thanks for your response .
Regards
Kiran

JAAS and JNDI (LDAP)

Hello,
I am using JAAS to connect to a Active Directory and login successfully (Authentication of the user). After the login, I want to get the users property like email address, phone number, ... from the Active Directory using JNDI. As I understand, to get connected to the AD with JNDI I have to use someting like:
env.put(Context.SECURITY_AUTHENTICATION,"simple");
env.put(Context.SECURITY_PRINCIPAL,ldapUserName);
env.put(Context.SECURITY_CREDENTIALS,ldapUserPassword);
My Problem is now, that I would like to take the user, which has connected to the AD with JASS for accessing the AD, but I do not have the ldapUserPassword from the JAAS Principal (the logged on user).
Is ther a way to use the current logged in user as LDAP (JNDI) user, or another way, to access the requested proeprties?
Thanks and Regards
Stefan

If had excatly the same problem.
In my my case I had a domain "testdomain.mycompany.com" and a domain controller "domaincontroller.mycompany.com" (maybe this is a misconfiguration?)
So I have set in the kerberos config file
[realms]
        TESTDOMAIN.MYCOMPANY.COM = {
                kdc = domaincontroller.mycompany.com
        }and the lpad connection url to "ldap://domaincontroller.mycompany.com/dc=testdomain,dc=mycompany,dc=com
This resulted in the error you have descibed.
Finally I put the following entry in the hosts file on my local PC
192.168.0.10 domaincontroller.testdomain.mycompany.com (192.168.0.10 is the ip address of the domain controller) and then it worked!
