There are multiple domains with trust relationships in between users of which need to have access to Legal Review.
Legal Review is able to authenticate users from multiple domains. To enable searching of multiple domains, the <DomainsToCheck> key in the 'Web.config' IIS configuration file located under '\Program Files (x86)\ZyLAB\EDiscovery\Ediscoveryservice\' has to be updated with the name(s) of the domain(s) and optionally with the user's credentials.
<add key="DomainsToCheck" value="user:pass@domain1,user:pass@domain2" />
<add key="DomainsToCheck" value="domain1, domain2" />
User and pass are the credentials of a user with administrative access to the domain. User and pass values are optional. Domain is required.
