Labs3 Stable multiple LDAP Chaining Configuration

[rxm307]

I've tested authentication to a single LDAP server successfully but now I want to chain several Ldap servers together, I've been following the instructions from http://wiki.alfresco.com/w/images/0/0b/Install_Configure_Alfresco_Lab3Stable.pdf
on "Chaining multiple LDAP servers"
but as soon as I load the config for chaining-authentication-context.xml

if I roll back this config to the default chaining-authentication-context.xml from chaining-authentication-context.xml.sample alfresco loads correctly although without any LDAP authentication

[rxm307]

If I use the config from here I can chain Alfresco Auth & LDAP

http://nix.theism.de/alfresco-authentication-with-openldap-on-debian-etch/

but what I really need to do is chain several LDAP servers together

[rxm307]

I've now lodged this as a bug in JIRA

https://issues.alfresco.com/jira/browse/ALFCOM-2645

[rxm307]

Tried this again this time with Enterprise 3.1 Trial and with the updated documentation at http://www.alfresco.com/products/ecm/enttrial/files/installing_configuring_alfresco_ecm3_1.pdf

and this appears to only authenticate to the first LDAP server in the chain and none of the others

[webrat]

I'm experiencing the same probles as the user in the first post does.
Is there already a solution (maybe an fixed configuration) there?

I was able to get this working in Alfresco Labs 3.2 Preview #1, but it looks like Preview #2 is out……..
