Authenticating against both RDBMS and LDAP in WL6.0

Question

Hi,
We are designing a webapp that will be accessible to both internal and
external users. For internal users, we would like to authenticate via LDAP;
for external users we would like to use RDBMS. In WL5.1, this looked to be
possible with the DelegatingRealm, however this has been removed in WL6.0.
Two questions:
1) Why was it removed?
2) How can we get this functionality in WL6.0?
Thanks much for your help,

Answer 1

We are currently deployed on WL5.1 with a similar situation as you and in
the process of migrating to WL6. We are Authenticating against LDAP and
Authorizing against RDBMS. But I can't see how you could tell it to go
one way for certain users and another for other users.
The delegatingrealm in WL5 was intended to split the responsibility of
Authenticating to one source and Authorization to another. To make this
work for your Application of splitting internal and external users
security, I suppose you can do it if you can somehow pass the information
to the Security Realm the type of the user that is logging in. Maybe you
can make this code a part of the userid such as ext_uersID or int_userID.
Doing this will allow you to filter the where the users are coming from
and Direct them to the appropriate security realm.
As far as WL6 goes, the Delegating realm class is no longer available
since the security model for WL6 is different from WL5. But you can take
a look at what they did with the RDBMSrealm example and use that. This is
what we did to make our Security work in WL6. However, you can no longer
store ACLs in the RDBMS realm in WL6.
Hopes this helps.

You will need to create a Custom Realm which delegates to both your RDBMS
and LDAP perhaps using the Weblogic supplied RDBMS and LDAP realms
