I am trying to upgrade one of our XServes from Snow Leopard Server to Lion Server and am running into a strange issue with our Active Directory based users and Groups.
The current Snow Leopard Server serving files from a XSan volume is running fine, though we find a very long Lag time for Windows users to connect. Once a few users have connected the lag seems to go away, but it is still not nearly as fast as Mac users connecting or Windows connecting to a PC server.
So I have connected a second Xserve to the SAN and performed a clean install of Lion Server. Initially while it would find my Active Directory Groups it would not import any of the users, so obvioulsly no one could connect. In a last ditch effort I installed the beta of 10.7.4, which seemed to resolve the issue for a small group of test users. However as I expanded the test I found that some users would get a message that the were no resources available to them, or they didn't have the correct permissions. This is very strange as everyone is in the same group so should have the same permissions. As a test I took one of the user accounts and created a new share and gave him R/W permission to that share and suddenly all of the shares that he should have had permission to in the first place popped up.
The only thing that I can think of is that we have such a large Active Directory structure that the authentication is timing out or reaching some user limit and stops looking. (we have over 50,000 users and thousands of groups spread through multiple OUs in the AD structure)
The new Server.app in Lion looks nice, but it does not seem to have nearly the robustness of the previous Server Admin tools. For instance, I never needed or wanted to setup a "Golden Triangle" but with Lion it is required. Perviously I could search for AD users or groups and drag them from the search window to the share to assign permission, now even though I've imported the groups and users it needs to search the entire directory when assigning permissions - why can't it see the groups that are already there? Why can I run a dscl search and find a user or group instantly, but the Server.app hangs for 5 minutes and shows 0 results?
Has anyone found a way to make Lion Server work in an enterprise environment?
