Karl Wright commented on CONNECTORS-460:
----------------------------------------
So, how is SharePoint configured to authenticate users who log into it? What
domain controller does it use for authentication (i.e. what domain is the
SharePoint server(s) joined to)?
I am not an active directory expert, but I've never found any indication that
you can join a Windows machine to more than one domain. I presume, therefore,
that the joined domain controller delegates authentication to the external.com
domain controller. If that is that case, everything might already work for you
if you simply specify the internal.com DC in your active directory authority
connection.

> Key: CONNECTORS-460
> URL: https://issues.apache.org/jira/browse/CONNECTORS-460
> Project: ManifoldCF
> 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
> Reporter: Colin Anderson
> Labels: active-directory, authorization, security
>
> 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.
