Custom Realm Bug in WebLogic SP3?

I recently upgraded WebLogic 6.1 from SP1 to SP3 and am now
receiving a ClassCastException when invoking the checkPermission
method on a Custom realm ACL that extends weblogic.security.acl.AclImpl.
This code worked fine in SP1. It seems that other developers
have experienced this problem when applying service packs to
WebLogic 5. Any one else encountering this problem with
WebLogic 6 and what is the workaround? (Stack trace attached)
TIA
[aclimplexception.txt]

I was unable to determine the cause of the problem, but I was
able to identify that AclImpl was changed between SP1 and SP3.
I updated SP3's weblogic.jar with the weblogic.security.acl.AclImpl
class in the weblogic.jar from SP1 and the exception went away.
I did not see anything in the release notes for SP2 and SP3
that indicate what may have changed. Does anyone know?

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
"<Jan 16, 2003 4:07:02 PM EST> <Error> <HTTP> <101256> <The run-as user: wlisystem,
for the servlet: ApplicationView for the webapp: /WLI_AI_Workshop_Control_Web,
could not be resolved to a valid user in the system. Please check if the user
exists.

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.
Thanks

Kiran,
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.
Thanks

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:

Subject: Re: Do Custom Security Realms have to use Mbeans?

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.

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

You should make your user that you use to startup the server a member

In other words there should be a Principal "Administrators" in the

I'm not sure if you can configure this afterwards but this is how it's
done out of the box.

We are working with a Platform domain on Weblogic 7.0. When you implementa custom

In our case we used the Custom Realm only for authentication. ACLs storeall the

like system, administrator are already part of the ACLs with the appropriateprivileges.
Please let me know if you have any suggestions.

Policy Director Custom Realm for Weblogic

I would like more information on how the Policy Director custom Realm for Weblogic
works. What all methods are implemented and so on. If anyone could send me the source
code of the custom Realm that would be of great help.
Thanks in advance,

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>

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

Debugging a custom realm in WLS 6.1

Hi all. I'm trying to find out how to debug my custom realm. I first implemented
the DebuggableRealm and put log.debug calls in my realm. I then set the realm.debug
property to "true" when I start the server. Is that it? The javadocs on debugging
are very sparse. I wasn't able to find a javadoc for weblogic.logging.LogOutputStream.
I also found a DebugSecurityRealm attribute in the ServerDebug element in config.xml
but am thinking this is old (from 5.X?).
Are there any other documents I should be looking at? Thanks!

Thanks very much, Utpal.
I still can't find the class (or even the package for that matter) at
http://e-docs.beasys.com/wls/docs61/javadocs/index.html
And that sort of mystifies me. Still, your answer solves my current problem.
I still don't fully understand the ConfigurationMBean
stuff as a whole, and how they get bound to a particular realm; i.e. Do I need
to write a MyRealmConfigurationMBean, and if so, how do
I bind it to MyRealm?
Note that the code I originally cited casted a BasicRealm return type to a BasicRealmMBean;
It's not immediately apparent why one is
even castable to the other, since they are two interfaces that
are not on the same inheritance line (I don't think).
Thanks for your time. I appreciate your help.

Using fileReamd + custom realm w/ WLS6

Hi,
I would like to write a custom realm for WLS6.0, but I would like to
delegate to the fileRealm for WebLogic accounts, such as 'system'. Can
anyone suggest a straightforward way to accomplish this?
Thanks,

Duh. Momentary lapse of reason, please disregard.

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.

If you extend the weblogic.security.ldaprealmv2.LDAPRealm and implements
newAcl, deleteAcl, newPermission,

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

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,

no

Thanks in advance for any assistance.

auth-method BASIC with custom realm

I've set up my web.xml with <auth-method>BASIC, and I've defined a custom realm
for authentication. When I enter a valid userid/password at login, I can trace
authUserPassword() in my custom realm, and I can see that it is returning an object
which is a subclass of weblogic.security.acl.User, as it should. However, rather
than acknowledging a successful login and moving on, the login dialog is redisplayed,
(minus password). Further attempts to enter the same userid/password don't invoke
authUserPassword(), presumably since the "failed" login is still cached. What
am I missing?

Have a look in the web server log to see under what account the failed
accesses took place, that will help in identifying the cause.

Custom realm in wl 5.1

Leaves have created a custom realm based on the RDBMSRealm example in
weblogic. How does the user name and password propagate from the client to
the ejb. Do I need to put this info as a User in the context. Any help
will be great
Thanks

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.

Problem with Weblogic SP3

Hi everyone,
Lately we upgraded from Weblogic8.1 SP2 to SP3. After re-creating the domains, I installed the service with -DWeblogic.Stdout=d:\logs\stdout.log -DWeblogic.Stderr=d:\logs\stderr.log parameters during it's startup. To my surprise, I found weblogic logging stdout information in stderr.log !!
Now is this a bug? Or am I missing out anything that's new in Weblogic SP3. I visited the bea site and didn't get any info on that.
Can anyone please shed some light?

Hi,
The application consists of struts1.1 in the web layer.
All user entered data are wrapped in a map and using
dispatcher controller (session bean) the respective
business objectss (session beans - Tx attribute is
'Required') are called by passing the map data which
in turn, executes the business logic based on the user
provided data.
The session beans calling the entity beans to do
create/update/delete jobs in database.
To retrieve data from database, we are using iBatis
framework and queries are being fired from session
beans.
In some of the functionality, we are using stored
procedure (SQL server 2000), which are being called
from within session bean.
I think, wherever, we are calling SP from session bean.
some local transactions are being created, which I
could not identify so far.We did not create any nested
transaction within stored procedure.
Please ignore the same posting I did in another topic.
Regds.

I have two web applications running in the same weblogic domain. Can Ispecify two

The only way i could get the custom realm class called by the server if ispecify
it as
<Realm CachingRealm="LeherCacheRealm"
FileRealm="wl_default_file_realm" Name="wl_default_realm"/>
in the config.xml. This causes the weblogic users, such as "system" etc toget invalidated.

Custom Realm

I would want to write a Custom Security Realm, that uses
- NT domain for authentication and
- RDBMS realm for authorization
I do not see any API to access NT Domain users, should I use JCOM
Kindly Suggest. Thank you

Aseem,
Did you configure the Caching and file realms with your custom realm?
