Database Table and LDAP Authentication in the same repository?

Question

I'm wondering if it's possible to authenticate through database tables for some users and LDAP for other users. I can configure each one separately but I'm curious if anyone has ever successfully done both in the same repository.
Thanks,

Another thing to try is this. I don't have an LDAP server here but it worked for me without LDAP. I think it should also work with LDAP as it is the same idea. I don't think there is a way to have a conditional Init Blocks. Also you can't have two init blocks setting the same variable (USER in our case). But what you can do is to have two Init Blocks, one for LDAP authentication and the other one for table authentication. So you could have this scenario:
1) LDAP "authentication" init block sets custom variable LDAP_USER
2) Table "authentication" init block sets custom variable TABLE_USER
3) Final authentication init block (the real one) sets USER variable using something like this:
SELECT CASE WHEN ':USER' = 'SOME STRING' THEN ':LDAP_USER'
ELSE ':TABLE_USER'
END
FROM DUAL
WHERE CASE WHEN ':USER' = 'SOME STRING' THEN ':LDAP_USER'
ELSE ':TABLE_USER'
END = ':USER'
Note how I use the CASE statement both to return the user value I want the USER variable to be set and also in the WHERE clause to make sure no rows are returned in case authentication fails (which should return no rows to denote a failed authentication). Obviously you need to set the init block dependancies correctly. I did a quick test with users coming from two separate Oracle tables in 2 init biocks and it worked fine for me. Give it a try and let me know how it goes.
