Subject RE: LDAP authentication
Date Thu, 03 May 2012 23:54:22 GMT
I have managed some success by adding the lines to

redback.default.admin=archiva-admin (a real ldap account)
redback.default.guest=archiva-guest (a real ldap account)

However, if I start with that config form the start, I am unable to login as the archiva-admin
account (even if I set it to other names which don't exist in LDAP).

I've found I can work around it by:
Install clean
Add ONLY the redback.default.admin line above
Start Archiva
Open page, complete admin form.
On the following ridiculous page, it requests that I now CHANGE the password.  Pffft.
Stop Archiva
Put in place the and application.xml files as below into place - with
the addition of the two redback lines above, and then start archiva.

And things work.

Problem: This kind of setup procedure is untenable from a repeatable system build (disaster
recovery is important yo) persepective.

I suspect that my configs are off somewhere where I'm unable to login as the archiva-admin
LDAP account - if I'm able to resolve this issue without having to play config file musical
chairs, I'll be golden.

Subject: LDAP authentication


The documentation I've seen for configuring authentication via LDAP is sparse, inconsistent,
and out of date (Redback), so before I even go into the details of my problem I'll grant that
I may have missed something important.

I'm using the current/latest stable release of Archiva's Standalone, 1.3.5.

Here are the changes I've made from the default configuration (I haven't even tried to bring
the config and DBs from our existing 1.2.2 Archiva instance).

I can authenticate as admin just fine, when I authenticate as an LDAP user, I see in the logs:
==> wrapper.20120503.log <==

And in my browser:

Problem accessing /archiva/security/login.action. Reason:

Caused by:

        at org.codehaus.plexus.redback.struts2.action.LoginAction.webLogin(
        at org.codehaus.plexus.redback.struts2.action.LoginAction.login(
(continues, snipped)

And most disturbingly, further attempts to to open any page in archiva results in a similar
error, even when I attempt to go to the logout url directly, but that's due to the account
I've attempted to login as. When I open archiva in another browser, I can open archiva without

Any information, assistance, etc, would be greatly appreciated.
