Subject Re: Login Contexts NOT working
Date Sat, 05 Sep 2009 17:11:10 GMT
Hey David,

Thanks for the response. The community for Geronimo seems very small, so
it's quite a lonely struggle.

Either way. I finally got it right about 5 minutes ago, but yet again have
another problem. This isn't so much as a problem as it is an unreachable
feature.

Assume I get the IC as follows:

    Properties p = new Properties();
    p.put("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
    p.put("java.naming.provider.url", "ejbd://localhost:4201");
    // user and pass optional
    p.put("openejb.authentication.realmName", "KMSRealm");
    p.put("java.naming.security.principal", "quintin");
    p.put("java.naming.security.credentials", "pass");

    InitialContext ctx = new InitialContext(p);

I am able to login and have the method authorizations work as intended for
different users. The problem is that I use JAAS for the login and would like
to use my own LoginModule. Is there anyway to have the above method use JAAS
authentication with my own LoginModule?

Re. documentation, they are quite hard to find. They document the features
but it's not always clear that a given document is what you're looking for.
I sometimes read something and realize that a certain part of it might help
me. I am, however, documenting my struggles on my blog, so hopefully people
with similar problems can find an exact explanation on solving it.

Further I also usually keep wikis for projects I use up to date, and submit
patches for things I change. So whenever I get all these things working and
back on track I will be contributing to the project, whether in
issues/features requests being reported, documentation/source patch
submissions or wiki updates.
