Use another security realm

I don't remember how have I done it. Somehow I made me a 'file' based realm (name file) and then set in weblogic-application.xml
<security>
<realm-name>file</realm-name>
</security>and I remember that that was it...
but now... it gives me weblogic.security.service.InvalidParameterException: [Security:090396]Security Realm file does not exist ...
If i do the same thing with the defaul myrealm it works... I don't remember setting the file realm as default...
Do you know how can I change the realm for my application?
Thanks

Thanks Vishnu,
I made a stupid thing I added SQLAuthenticator to the default and the db instance is down ... now I have to manually remove it from config.xml

Using RDBMS Security Realm in production?

Hi,
In the BEA documentation it is stated that 'The RDBMS Security Realm is an
example and is not ment to be used in a production environment.'
However, of the Realms that are available this one seems to be best suited
for our needs, so I'm wondering if there is any specific reason why this
Realm should not be used in production. Has anyone had any experience using
it in a live environment?
I would be thankful for any information on this.

Is this possible to use no default security realm?

Hi,
I created new security ReadOnlySQLAuthentication provider in the default realm and it works. Now I have all the users from all applications in one realm. If they use the same enterprise roles, user can log to one application with login and password from another application. To prevent it I created another security realm. I've added ReadOnlySQLAuthentication provider, set in my application new realm name - in jazn-data.xml and web.xml. But it doesn't work. My questions are:
It is possible to use few realms? So one application will use default realm, another no default realm.
If so, how to bind an application to no default realm?

Hi,
A WLS instance only supports a single realm. So the answer unfortunately is no (was different with OC4J)

Errors encountered while using a Custom Security Realm on a 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,

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.

Hello Vikram,
Are you using the new WLS 7.0 security framework? It is not supported for
Portal 7.0. For Portal 7.0 apps you have to use compatibility mode (6.x
style) security.

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

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?

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.

Unable to use a custom security realm with Netscape Directory Server in WebLogic 7

I have all users and groups stored in a Netscape LDAP server (version 4.1.6 on
Solaris 8), so I want to create a custom security realm in WebLogic 7 (also run
on Solaris 8) which uses my LDAP server as the Authenticator. I tried this by
using the Admin Console and followed exactly the steps in Chapter 3 of the "Managing
WebLogic Security" doc. However, when I rebooted WebLogic and logged into the
Admin Console again and clicked the Users node under my custom realm, I saw this
message in the right-hand pane: "There are no Authentication providers available
that support the creation of Users". Also, I don't see my custom realm in the
dropdown list under mydomain -> Security tab -> General tab -> Default Realm.
What did I do wrong? Also, where does WebLogic store the custom security realm
info? It is definitely not in config.xml.

How can one use one specific security realm per application ? The realm-name attribute of the login-config tag of web.xml does not make any difference

Hi,
I have different sets of users coming from different databases and using different
roles mapping for each of my web applications. I would like to configure a specific
security realm per application in my weblogic server 7.0 . Is it possible ?
I try to specify the realm-name of the login-config tag from the web-xml deployement
descriptor but it doesn't make any difference. The default realm is always used.
I also would like to tell the Weblogic server to use the default realm in case
the realm isn't specified or isn't found. For example, the default would contains
my admin users.
Thanks a lot for your answer.
Iz

I thik this is a common mistake the ralm-name tag in the deployment descriptor is used
just by the browser for display purposes (when it opens the basic auth dialog box) so as
of now there is only 1 active realm which can have multiple providers as Kevin pointed
out
Kevin Lewis wrote:
WebLogic 7 now ignores the realm-name tag (I found that out yesterday).
My understanding is that there is only one realm active at a time for a domain
(I would be interested in being contradicted in this).
However, you can have multiple providers in each category of a realm: authentication,
authorization, etc. Therefore, what you can do is key authentication, et al,
off of some other information. We have our users enter their company, for example,
and use the TextInputCallback to get it. You could also encode something in the
initial page, based on the URL they hit, or whatever, and get that back in your
callback.
You can store that information in your own Principal implementation, and key off
of that in your authorization provider, going to a different database as appropriate,
or abstaining when a specific provider doesn’t have anything to say about a subject.
Anyway, there should be a way to do it, even if it's more complex than you would
have hoped.

Adding a user to the File Security Realm

Hello,
When I attempt to add a new user to the file realm with Application Server->Security-Realms->file-> Manage Users, I get the error:
A "com.sun.enterprise.tools.guiframework.exception.FrameworkError" was caught. The message from the exception: "Unable to get View for ViewDescriptor 'fileUsers'"
The root cause is "java.lang.ArrayIndexOutOfBoundsException: 0"
See the HTML source for more detailed (stack trace) information.
When I look at the file C:\Sun\AppServer\domains\samples/config/keyfile I see the new user added, but the Admin Console is not happy...
Please advise.
-- POC

There are some issues in admin gui for managing security service in beta.
I have verified that this has been fixed in FCS branch.
Since the user and password has been written to keyfile in your scenario, it may be OK.
You can try to use the user. If this is not working, then restarting the server should work.
Another way is to create user by using asadmin command. This is working fine in beta.

Conf. a Win2K Security Realm on WebLogic

     Hi! I'm having some problems configuring a security realm in WebLogic
server 6.0sp1.
     I'd like that WebLogic use the Windows2000 security realm as the
default security (it can be used as the secondary security realm
if it's the only way).
We've been trying to make it work for the last two (business) days
with no hope of being successfull at all.
     We are using the BEA documentation 'Managing Security' as reference,
and we have some doubts about what's in there.
First doubt:     The documentation says that we need to create new
security realm of the type Windows NT. OK, we did it. But we are
not sure about how to fill the filed Primary Domain. The documentation
says to put the host and port of the computer where User and Groups
are defined for the NT domain. I'm using the same computer for
both (NT domain and Web Logic), so I put the host name (babalu).
Wich port should I put?
Second doubt:     The documentation says to create a systerm user on
the NT domain using NT administrative tools, names it 'system'
and set some stuff for it. But windows 2000 already has a user
with that name (SYSTE, but capitalized) and the property that I
should set on it doesn't exist! By the way, on the system user
user that windows2000 has I wasn't able to set any property.
Last doubt (maybe should be the first one) : Does WebLogic 6.0sp1
support Security Realms from Windows 2000? Or I need to download
another plugin or somethign like that?
     Thanks for Reading and (hope) Answering my qusetions!

Hi! Thanks for the answer. I'll try to run WebLogic as a service.
In fact, I tried it before but I wasn't able to. I started the
service by hand, but I wasn't able to access the server. So, I
click on the 'remove web logic as service'(something like that)
in the WebLogic program group. Ok, it was removed. But when I tried
to put it back I didn't find no funny button to help me! Could
you help me with that?
Another thing. If I use NT Realm as a Caching Realm I'll be
able to see the NT user and users groups with the Web Logic management
GUI ?
Thanks once again,
Roberto Giordano Barra

Hi,
By saying win2k I am assuming you mean creating an NT
realm.
Do not bother specifying a port, just put the server name.
You have to ensure that you are running the weblogic server
as
a NT service if you want to use the NTrealm.
Make sure under Caching Realm you specify the NTrealm.
That should be it.
Hope this helps.

BEA public API (WLS6.1)for programatically updating default security realm?

Hi,
Does anyone know how to use BEA's public API to programmatically add/update WLS
6.1 user credentials in the default security realm? The API would of course
automatically persist the updates to $WLS/config/mydomain/fileRealm.properties.
Is there a way to do such updates by programmatically engaging the WLS security
realm related Mbeans? I basically need to do (from a deployed application component)
what is easily done from the WLS Console's [security->User->Add User/Change
Password] screen. Ideally, I could use the same API that the weblogic.security.acl.internal.FileRealm
command line utility (or wlshell also) uses to make updates. But I doubt that
the classes used by these tools are in BEA's public API for WLS 6.1. Especially
important to me would be the BEA API mechanism that takes a clear-text password
and hashes it to the encrypted format written in fileRealm.properties (and synchronized
w/ SerializedSystemIni.dat). Ultimately, I am trying to replicate a large
Oracle table of (*user, clear-text -password, group) records into the default
WLS security realm. Thanks for any insights.
Ben

Thanks to another's post, I have found the answer to my problem in the Girdley/Woollen/Emerson
book "J2EE Applications and BEA WebLogic Server" pp. 496-498:
Note: this code segment is for WLS 6.1 and this API is said to be deprecated
in WLS 7+
//Roughly outlined, assuming session w/ userName, groupName, password Strings
in HTTP Post request
weblogic.security.acl.CachingRealm realm = (weblogic.security.acl.CachingRealm)
weblogic.security.acl.Security.getRealm();
weblogic.security.acl.User u;
weblogic.security.acl.Group g;
u = realm.newUser(userName, password, null);
g = realm.getGroup(groupName); // use g = realm.newGroup(groupName) if groupName
does not exist in realm
g.addMember(u);
//log in the new user
int rc = weblogic..servlet.security.ServletAuthentication.weak(userName, password,
httpSession);
// use realm.deleteUser(u), realm.deleteGroup(g) as appropriate, etc.

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.

Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.

Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.
Disk Warrior / TechTool Pro 5 / Drive Genius 3 - top 3 probably
There are always going to be normal items you just ignore with Repair Permissions. Useful to do once in a while but not magic. Same with SMC and the rest. Running disk repair is one of those things that it seems should be done before there is trouble, not after, and a weakness in HFS file system and disk directory.
Apple Support is a good place to start looking and then hardware category.
http://www.apple.com/support
http://www.apple.com/support/imac /macbookpro etc
Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?
You can overheat a hard drive with needlessly running 7 and 35-write pass, besides which the best way to map out bad blocks is not Disk Utility.

I'd direct your replies to iMac and MacBook Pro as well as to Using OS X Snow Leopard areas.

How to implement a tree like security realm?

hi all:
i am working on a project . it's a very complex one and most importantly there's
so many
functions( 1000 or more) and every fuction should be protected resources. so i have
to define many roles and map the roles to the many functions. it's a very tiring
job and
i am not sure the role to function mapping is stable one. because the mapping is
saved in
a xml file and this file is depolyed with the application, so if there s any changes
we have to redeploy all the application and restart the server.
there s still another problem. we want security realm to be a tree instead of
a flat one( weblogic's group is a flat one ) . if we assign a node to a role all
its children
belong to the same role.
so is there way to do this. any solution?
regards
daniel wang

maybe you could exploit the way ACLs have dotted names to reflect your tree
structure, so the acl root applies to all functions, root.branch1 only
applies to functions on branch branch1, and root.branch1.branch2 applies to
functions on branch2 of branch1. there´s an api that gets the most specific
acl given a path to a node.
i'm not it´s acls that you want to correspond to nodes, but maybe you can
work out some kind of scheme that gives you what you want.

Making a new Apple ID is not a good idea, since you have to reset the password for that Apple ID anyway. All of your purchases are tied to the Apple ID that the iCloud account was created under. So, you have to retrieve the password for that Apple ID in order to sign into iCloud anyway.
Go to Manage your Apple ID, and click on the Reset Password option (Apple - My Apple ID). Sign on with the Apple ID that the iCloud account was created under, and answer the security questions. If you do not remember the answers to the Security Questions, contact Apple Support to have them reset:

Use another security realm
