Hi Colin,

The prefixes are not the issue.  In ManifoldCF, there should be one authority that is capable of dealing with all the interacting domains, just like SharePoint understands all the domains by talking with just one domain controller.  An authority's job is to look up the SIDs for a given username, and since your SharePoint instance can do this by talking with only one DC, ManifoldCF's active directory authority connector ought to be able to do the same thing.

The issue, then, is that the active directory authority connector doesn't know how to deal with external, trusted domains.  The authority must locate the DC(s) for these domains within LDAP (I believe) and route requests to the appropriate DC.  Alternatively, if automatic discovery of the external DC is too hard, we can modify the AD authority connector to simply allow the user to describe multiple domain controllers.


Does this sound reasonable to you?

>          Issue Type: Improvement
>          Components: Active Directory authority, Authority Service
>         Environment: Two Active Directory domains: {{internal.com}} and {{external.com}}
> I'm indexing a Sharepoint site, where that site has permissions set from_both_domains

> The ManifoldCF authority service doesn't handle multi-domain environments.
> The authority service returns a list of SIDs for the specified user, from all available ManifoldCF authorities, for example:
> {{TOKEN:InternalAD:S-1-5-21-1234567890-1234567890-1234567890-1234}}
> Note that the SID is prefixed with the name of the ManifoldCF authority.
> Here is my setup:
> Output connector: Solr
> Authority connector1: Active Directory ({{internal.com}} domain), named {{InternalAD}}
> Authority connector2: Active Directory ({{external.com}} domain), named {{ExternalAD}}
> Repository connector: Sharepoint
> If I set the Sharepoint repository connector to use the authority 'None (Global Authority)', then {{allow_token_document}} will contain SIDs that are _not_ prefixed with any authority name, for example:
> {{S-1-5-21-1234567890-1234567890-1234567890-1234}}
> It is therefore not possible to get any search results, because the authority service tokens will not match the stored tokens (because they _are_ prefixed with authority names).
> If I set the Sharepoint repository connector to use one of the AD authorities 'InternalAD', then {{allow_token_document}} will contain SIDs that are prefixed with 'InternalAD', for example:
> {{TOKEN:InternalAD:S-1-5-21-1234567890-1234567890-1234567890-1234}}
> However, the prefix is _always_ 'InternalAD', even if the user/group actually belongs to the {{external.com}} domain. Therefore it is not possible for users in the {{external.com}} domain to get any search results, because the authority service tokens will not match the stored tokens.
> In essence, there seems to be a mismatch between the tokens that the authority service outputs, and those that repository connectors output.
> Perhaps one solution would be to use the authority 'None (Global Authority)', and modify the authority service to take an extra query parameter that prevents it from prefixing SIDs with the authority name.
