Greetings all. I have an integration problem I'm hoping someone might have some insight on. *Here’s the situation: *Merger Closed Friday. Integration in progress. Need to publish Citrix apps to both companies users. *Citrix Setup: *One farm CPS 3.0/Windows 2003, one farm XenApp 5/Windows 2008 sp2. Both have the same issue. ** *AD set up:* Our users are in a domain with an empty forest root above it. Their users are in a domain with an empty forest root above it. A trust exists between the two forest roots. *Problem:* To publish apps to the other domain I **should** be able to publish Citrix apps to a domain local group in my domain, and add users from both domains to that domain local security group. What I am seeing is that for applications published to a domain local group, users in that group from our domain see the app, but members from the other domain do not see the app. I can publish the application explicitly to users in the other domain and they can see and access the application. This is not an optimal approach. Trying to get the domain local group working for all users. Has anyone run into this issue before and do you have any recommendations? Thanks for any help you can offer. Best regards, Christopher
