I like to use OpenLDAP to authenticate my Oracle users. It should be possible to fetch at least the password from the directory.

There appearently is something for the Oracle LDAP servers, but would it work with OpenLDAP (plain, from i.e. Debian)?

Thanks for the quick upvote, but hold off on accepting for at least 24H, you might get some better answers in. – Brian Ballsun-Stanton Jan 6 '11 at 10:52
Good idea. Let me change it back for a couple of hours. – Sebastian Roth Jan 6 '11 at 10:56
Did you get this up and working? – ik_zelf Apr 12 '11 at 13:38

According to this post, you absolutely can, with significant speed improvements over OID.

Looking at this absolutely ancient post, it was apparently possible back in 2003.

Here's the Archive.Org transcript of the page they reference.

This is a Oracle documentation link about hooking OID up to an "external directory". Good luck.

Has anyone gotten Oracle user authentication with OpenLDAP working? any technical details published anywhere? I read the links above, but while some of them do claim success, there don't seem to be any technical details. Also, I've been Google searching, to no avail. – Mark J. Bobak Apr 17 '15 at 19:41

There's a page describing step by step how to set up OpenLDAP to resolve TNS aliases.

Well, the procedure's quite lengthy, so reposting it here was not really possible. Plus, it's actually a better answer to the question than anything I've read here. – Fred Petillot Jul 21 '15 at 11:57
@FredPetillot and when that page moves somewhere else or just stops being there, your answer will contain zero bits of information. – dezso Jul 21 '15 at 12:39
