Custom Realm using LDAP?

Hi,
has anyone implemented a custom realm using LDAP? I was suprised to learn that
ACLs are not supported in the LDAPRealm. Our corporate direction is to have a
central LDAP security store - including ACLs. Unfortunately the LDAP server is
MS SiteServer! Anyway, I assume this means I need to implement a custom realm
- unless there is an alternative.

You are correct - you'll need to write a custom
realm to do this.

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

I tried using Windows NT as a security realm but that gave me errors too.
Does anyone has any experience using anything other than the default Realm?
Any help would be appreciated. Thanks!

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.

Hi ,
I am implementing a simple custom security realm using LDAP as the

My question is (a custom realm newbie question) ;
Is it possible to use weblogic.security.acl.Security with my custom
realm to check permissions, get the current user,etc.,
OR
is this class ONLY used with default realms (when ACL is stored in a

Help with Weblogic 6 sp1 Custom Realm !!!!

We are trying to run Weblogic 6.0 sp1 with our current environment (ejb 1.1, custom
security realm)
We can compile and deploy our ejb 1.1 beans. We wish to start with ejb1.1 and
move to ejb2.0 once we can get our custom security working.
The JDBC connection pools are fine.
Our custom security realm uses LDAP for user authentication and an Oracle table
for authorization (acls).
Earlier, I wrote to the board and received the below following instructions to
use our existing custom realm in wl 60. You can read below, but I followed these
instructions on Solaris 5.6.
1. I ensured the SunOS patches were up to date.
2. We ensured the LD_LIBRARY_PATH reflected weblogic 6 (and not 5.1). We moved
the 5.1 classes over to wl6.
3. We copied our custom realm properties file to the weblogic root and/or the
config subdirectory (tried them both).
4. We ensured the security realm class we wrote is in the classpath (we bunch
all our serverside classes in a jar file anyway).
5. Then we created a custom realm via the console – name BFXRealm and it’s
class name <package>.BFXRealm, left configuration box blank.
6. Then we created a custom caching realm BFXCachingREalm and set its basic realm
as the custom realm, BFXRealm. All of the enable caches are checked to true.
7. Then we set the default realm to the BFXCachingRealm.
Now, when we perform a query, the everyone group should be implied. We don’t
implement LDAP lookup on queries. If I try to run a query from a client, I see
the client box connecting with the server:

Yes this can be done. Here's how:
1) I'll assume that the classname to your custom realm is "com.yourcompany.YourCustomRealm"
2) I'll assume that your custom realm has some kind of properties file from which
it reads its configuration data. Let's call this file "YourCustomRealm.properties"
3) Copy YourCustomRealm.properties to every machine that you're running wls on
(you are probably already doing this today).
4) Make sure that com.yourcompany.YourCustomRealm is in the classpath when you
start wls (you should already be doing this today)
5) In 5.1, there used to be some utility classes that customers used for their
custom realms - something about Pools & Factories. These have been renamed in
6.0. If you're using these classes, then go to your 5.1 weblogic jar file and
pull out these classes and add them to your classpath for 6.0.
6) In the console, create a custom realm and set it's realm class name to com.yourcompany.YourCustomRealm.
Leave the configuration data section blank.
7) In the console, configure your custom realm as the alternate realm. That is,
create a caching realm and set it's basic realm to your custom realm, then set
the realm's caching realm to the caching realm you just created.
I'm pretty sure this should work for you. We did this to provide a patch that
let 6.0 users uses the LDAPRealm rewrite from 5.1.
The downside is that you don't get single point of administration - that is, you
have to make your custom realm's configuration data (YourCustomRealm.properties)
available on all the machines you're running WLS on. If you rework your custom
realm, then the configuration data gets put in the custom realm configuration
you create via the console and automatically copied to other machines for you.

Accessing custom attributes in LDAP using WD Java - UME APIs

Hello Friends,
I am trying to access a custom attribute from LDAP in WebDynpro Java. I am using bellow code.
IWDClientUser clientUser = WDClientUser.getCurrentUser();
IUser sapUser = clientUser.getSAPUser();
if (sapUser != null) {
String[] str_emp = sapUser.getAttribute(<Name Space>,"Attribute Name");
if (str_emp == null || str_emp.length == 0) {
wdComponentAPI.getMessageManager().reportSuccess(" NULL ");
return;
} else {
strEmpID = str_emp[0];
wdComponentAPI.getMessageManager().reportSuccess(strEmpID);
The name space is "$usermapping$". I am not sure why it is like that only for this attribute i am trying to access.
I am getting null value if i run this code.
Can any one help
thanks
Shobhan

Hi,
Are you sure this is the right namespace? The default namespace is com.sap.security.core.usermanagement.
You can get all namespaces and the names of all attributes defined for a user using methods getAttributeNamespaces and getAttributeNames : [Interface IPrincipal|http://help.sap.com/javadocs/NW04S/current/se/index.html].

Custom Realm for SJSAS 9.x using JAAS documentation too vague

Hello there,
I am trying to implement a custom realm for a particular web application on my SJSAS 9.x server. So far I have been unsuccessful and receive the following message in my server.log:
[#|2006-10-20T13:51:56.390-0300|INFO|sun-appserver-pe9.0|javax.enterprise.system.core.security|_ThreadID=11;_ThreadName=httpWorkerThread-8080-1;javious;|SEC5046: Audit: Authentication refused for [javious].|#]
The documentation I have been using for reference is at:
http://docs.sun.com/app/docs/doc/819-3659/6n5s6m58k?a=view#beabs
However, I have a number of questions.
First of all, this section referenced by the URL above is identified as "Creating a custom realm". Then the second sentence of this section states "Note that client-side JAAS login modules are not suitable for use with the Application Server". Does this not mean that JAAS login modules are not suitable for use with SJSAS web applications since they are components of the Application Server? Is there a reason for providing information on creating a custom realm for this application server in which it is not suitable for? Why isn't it suitable for the application server? What if I want to implement my own realm for my web application so that I can maintain my application users separately in another application?
Secondly, this section explains that I can create a custom realm simply by creating a custom JAAS login module and a custom realm class. It then goes on to explain how to construct these classes and what to include in them. Notably, the documentation states the following:
The authenticateUser() method must end with the following sequence:
String[] grpList;
// populate grpList with the set of groups to which
// _username belongs in this realm, if any
return commitUserAuthentication(_username, _password,
_currentRealm, grpList);Having looked at the API for authenticateUser I discovered that it is a void method, however the documentation states to return a value from "commitUserAuthentication(..). Also, my commitUserAuthentication method only excepts a single argument of type String[] representing a list of group names, therefore I am unable to supply the additional arguments as documented. This is confusing.
Once finished reading the documentation, I am left hanging with hardly a clue as to what to do with these two new classes. Now having implemented a custom login module on Tomcat 5.x in earlier days, I did happen to have some experience to know to edit the security.properties, policy, and login.conf files. So anyhow from here I end up stumbling blindly through configuration of my domain1/login.conf and domain1/server.policy files. I also attempted to add my new realm within the admin console under security/realms and dropped my new jar file (with two classes) into the app server lib directory.
All in all, this completely fails to work. I have even placed System.out.println statements in all of my implemented methods and none of this actually shows up in my server.log file. Why is this section so vague? Why isn't there a step-by-step example from start to finish of how to implement a simple custom realm in SJSAS9?
Does anybody have any helpful suggestions?

Well, once again, I'm going to have to provide my own answer.
After much waiting and then deciding to invest much time researching documentation and tracking down information to assist in my solution, I have manage to find the golden egg for my own recipe of a solution.
In addition to the very helpful info I have found at:
http://developers.sun.com/prodtech/appserver/reference/techart/as8_authentication/index.html
I have mange to get my custom realm to work with the additional configuration of my sun-application.xml for my ear file. Even though I only wanted to specify my custom realm for my web.xml file, it turns out that in addition to this, I had to also define it in my sun-application.xml file (manually in XML text mode - within Netbeans 5.5) as follows:
<sun-application>
    <realm>mycustrealm</realm>
    <security-role-mapping>
        <role-name>mycust_role</role-name>
        <group-name>mycust_group</group-name>
    </security-role-mapping>
</sun-application>

Using fileReamd + custom realm w/ WLS6

Errors encountered when trying to use a Custom Realm on BEA Weblogic Platform Domain .....

Hi,
We have created a WebLogic Platform Domain. A WebLogic Portal application(Portal
7.0) and some Web Service apps are running on this domain.
We have created a Custom Security Realm b'cos of our application requirements
and now when I startup the Platform Domain, I see lot of errors.
Some of the errors typically are

Do we have to create any predefined user accounts in the Security Store to get
rid of these errors. I would appreciate if anyone can suggest some tips or workarounds
for configuring or creating a Custom Security Realm for Web Logic Platform Domain.

First time around, the Custom realm was not authenticating the user. I gotthe
code to authenticate the user successfully. Now the WebLogic serverwouldn't even
start. It would give me an error message which says "User System is notauthorized
to boot Weblogic Server". For your reference, I am attaching the Log file.My
custom realm classes output some debugging statements in the log file.From the
log file u will see that the users are getting authenticated successfully.
Please let me know if you have a custom realm working for you. I might bemissing
something.
Appreciate your help.

Java ftp server which can use LDAP, how to integrate with WLS' implementation of LDAP?

Howdy.
I'm setting up a java ftp server
(http://www.mycgiserver.com/~ranab/ftp/index.html) which is capable of using
LDAP for it's user security. I would like to integrate this ftp server with
wls' implementation of LDAP so I only have to admin one user list.
Does wls put it's user list in the LDAP or in it's own proprietary setup? I
tried playing around with it, but the users don't seem to appear in the JNDI
tree. Is this where the LDAP stuff is located? I thought it was in there?
If it's in it's own setup, is there a way to propagate the users to LDAP?
If these look like newbie Q&A, I guess they kind of are, I'm new to LDAP.
Thanks for any input you might have.

Peter,
If you are talking about using the embedded LDAP server in WLS 7.0 for this purpose
I think you are going done the wrong path.
Look at the following URL on how to use an external LDAP server for your custom
application

Authorization with custom realm

Hello,
I have created a custom realm to access user and role information stored in a database. It is working fine for authentication. However, the Subject, Principal, and roles/groups do not seem to be used for later authorization steps. How should this information be stored so that the containers can access it?
In particular, when enabling security constraints in web.xml to limit the access of a particular url to a particular role, that url can never be accessed. The server generates messages implying that the user is not logged in:
Checking Web Permission with Principals : null
Checking with Principal : nonlogin-principal
Any suggestions on how to appropriately store the login information would be appreciated.
Thanks!

I have had a custom realm that handles ACLs since 5.1. My question is I want to
mix it with the out-of-the box ldaprealm v2. I was hoping for a failover mechanism
where I can supply a custom realm that knows how to authorize and leave it up
to the canned ldaprealm to authenticate. The filerealm behaves in such a manner,
does it not.
I will try your idea about extending the ldaprealm. But, the challenge will be
in dealing with the delegate.

Why don't you use the Custom Security Realm? You can construct an ACLin a

Is there a way in 6.1 to use the supplied LDAP Realm V2 for
authentication
and
managing groups, but enhance it with ACL's (stored in a database)
for
authorization?
Obviously, I would like to take advantage of the server's caching
realm
capabilities.
I currently running a custom realm (from 5.1 which works in 6.1)
that
mixes LDAP
authentication, group management, and DB ACL's for authorization,
but I
no
longer
wish to capture the user's password (due to sorporate policies) and

to avoid maitaining the authentication code.
Thanks in advance for any assistance.

My own Realm instead of Custom Realm extends IASRealm ?

I understand that the custom realm the sun app 7 offers is an extension of ISARealm where authenticate() is overloaded.
But authenticate() does only return a list of groups.
I want to return my own User class with interface Principle.
May I implement my own Realm implementation as a substitute for IASRealm, LdapRealm etc. ?
I know how to implement a JAASRealm for Tomcat because I did it and I want to use it on sun app 7 too.
Thanks,
Frerk

I don't know for sure, but I would suggest changing the user.dn
attribute. For example, I had o= yyy, ou=xxx, ou =xyz in LDAPV1 and in
LDAPV2 I have ou=xxx, o=yyy. So, I had to drop one 'ou' and put the ou
first.

Hi,
When migrating from Weblogic 6.0 to Weblogic 6.1sp1 I want to use a
Custom Realm instead of the deprecated LDAP Realm. We are using
Netscape Directory Server 4.1. So I modify the Netscape template. I
get no warnings or errors when starting WLS and my groups are listed
in Groups in the Console. But when I try to authenticate a user
authentication fails. When I set up a LDAP Realm as before it succeeds
for the same user and operation.
I have browsed this usenet group without finding the solution. Do
anybody have a clue?
Here is the entry in config.xml for the Custom Realm:
<CustomRealm
ConfigurationData="user.filter=(&(uid=%u)(objectclass=person));user.dn=ou=People,
o=entraoslo.entra.no;membership.filter=(&(uniquemember=%M)(objectclass=groupofuniquenames));server.principal=uid=admin,

Name="TakeCargoRealm"
Password="{3DES}ptTZvPU0y3CR76DZQZ8pqw=="
RealmClassName="weblogic.security.ldaprealmv2.LDAPRealm"/>
The entry in config.xml for the LDAP Realm:
<LDAPRealm AuthProtocol="simple"
Credential="{3DES}ptTZvPU0y3CR76DZQZ8pqw=="
GroupDN="o=entraoslo.entra.no, ou=Groups"
GroupIsContext="false"
GroupUsernameAttribute="uniquemember"

How to access "Alternative Realm" or "Custom Realm" from components like Servlet ?

Hello,
Says if I have alternative realm or my custom realm which implement
"ManageableRealm" interface. How can I access the realm from other
component, like Servlet or EJB in same WLS ? I tried using code like this
BasicRealm realm =
Realm.getRealm("XmlRealm","weblogic","myclass.DebugRealm");
if (realm != null) {
Class realmClass = realm.getClass();
out.println("Realm is " + realmClass.getName());
Which "myclass.DebugRealm" is classname of my own realm. This realm works
fine when using for authentication and authorization. But when I run this
code on servlet, it seems that it doesn't return the realm it created when
starting WLS, I mean the one that served authentication and authorization.
But it create a new instance of this class (I knew it 'cos I put debug
message in its constructor). So how can I get reference to the realm
instance which is created when starting WLS ?
Thank you in an advance,
Siros

Hello again,
Sorry to say that now I've got the way. I post here again for someone who
may face that same problem.
So strange that, I just changed the realm name in below code to "custom" and
then it works !! My realm is extended from "AbstractListableRealm" class and
I think I named my realm as "XmlRealm" in it constructor by call
super("XmlRealm");
But seems like its "getName()" method always return "custom", so in servlet
code, it' rather be.
BasicRealm realm = Realm.getRealm("custom");
if (realm != null) {
Class realmClass = realm.getClass();
out.println("Realm is " + realmClass.getName());
This works fine and no instance of realm is created. Anyway I saw that
constructor of "AbstractListableRealm" take String argument for "name" of
the realm. So why it's always "custom" ???
Comments are welcome,
Siros

Connecting to PAPI Process Service when using LDAP

We have Oracle BPM 10.3 set up with using LDAP as the directory for participants. In order to connect to the PAPI process service we want to use a system id that is a non user but set up in LDAP. How do we do this? Is there any special role or security group needed for this user, i.e. does it need Process Admin user privileges?

HI
Yes, this definitely will need a password, which is the same as the password you will use to log into the system (BPM Workspace or the external application that makes PAPI calls).
The way we have implemented this is: We have an external J2EE application (app A) that makes use of the papi calls, deployed on weblogic. The BPM engine is also deployed on the same weblogic domain. THe BPM application can then be configured to be used in the Single Sign On mode and deployed. In such a scenario when the user types in the url for the BPM workspace, the login page for app A will be shown.
THe LDAP that you use to configure the BPM directory, can also be used to create a security provider in the security realm of the weblogic (using weblogic console). THis will ensure that any application (in this case app A) deployed on weblogic will use this users/groups from this LDAP for authentication purposes. This completes the setup, so we have app A and BPM application both authenticating against the same LDAP and BPM application is configured in SSO mode.
When the user comes to the login page of appA, the corresponding servlet can store the password in the session and then forward to the worklist app page (if you want that). The BPM login page will NOT come up, since BPM can authenticate the user based on his login into appA. Later (let us say during the external task execution; when the servlet of appA is called from BPM), you can use the password stored in the session to create the papisession object for the logged in user.
Recently I started a blog, where I have an example of PAPI (as this is one of the favourite questions of BPM users). YOu can check it out

Custom realm in wl 5.1

I have a web app that uses BASIC authentication.
What I want is for the standard web app login box to be used,
but then I want to use a custom database table to verify the usernamepassword.
How do I do this in weblogic 8.1.On dev2dev, there is a sample dbms authentication provider that you can use
as a starting point
for a custom provider. You then configure this authentication provider in
WLS and authentication
will be handled by your provider.

While implementing sample custom realm, got ClassNotFound exception

I am trying to get the sample custom realm work. I followed every step in the documentation and had it deployed successfullyl. When I tried to log in, the authentication failed. Then I restarted the SunOne appserver, in the server.log file I got the error:

Since I am new to this, I couldn't locate the problem after checking everything many times. Can anyone help me? I need to get this part work first, then I can move ahead and make changes.
Thanks a million!

Thanks a lot, I did it and it worked.
I have more questions. For the custom realm database, I want to use a table just for username and password, and another table just for roles. Then use a third table as a bridge between the two. Can I do it in the sample application? Can I change JDBCLoginModule to do this? If yes, Where to put JDBCLoginModule and JDBCRealm after changes?
Really appreciate your help.

WebLogic Server doesn't start after configuring a Custom Realm

Hi,
We are having problems getting WebLogic server to startup after configuring a
Custom Realm. It outputs the error message "User System not authorized to boot
WebLogic Server. Security Excpetion".
For debugging purposed we had our Custom Realm classes output some debug statements
to the console. From the output it was apparent that all the users were getting
authenticated properly including System, Administrator, wliSystem etc. But after
the initial authentications we get this error message. I am attaching the log
file for your reference. Do we have to implement Authorization also (by implementing
ACLImpl) in the Custom Realm. Our Custom Realm was planned to be used only for
authentication.
Appreciate any feedback on the cause of the problem.
Thanks

Thanks Deyan. I will give it a try and let you know.

You should make your user that you use to startup the server a member
of
the Administrators group.
In other words there should be a Principal "Administrators" in the
Subject that your LoginModule returns.
I'm not sure if you can configure this afterwards but this is how it's
done out of the box.

Mike,
We are working with a Platform domain on Weblogic 7.0. When you implementa custom
realm it can be implemented just for authentication and not for authorization.
In our case we used the Custom Realm only for authentication. ACLs storeall the
authorization information. We assumed that the standard Weblogic useraccounts
like system, administrator are already part of the ACLs with the appropriateprivileges.
Please let me know if you have any suggestions.
Thanks

The second is defined by ACLs or something, which is probably (most

like 7, grey area for me).
