Hey folks! We're evaluating JIRA in our organization and it is absolutely spectacular. However, we're running into an issue just after migrating from the hSQLDB to MS SQL Server 2005. Not sure if that's the culprit, but as far as I can tell we didn't encounter this issue until the migration.
Anyway, the problem is that whenever we encounter a field that relies on the autocomplete for user names, it doesn't seem to return ANY matches:

Since there's no way to bring up the full user search dialog (which works fine, by the way), we're really stuck here as we can't add any users to our project roles.
So I'm just trying to figure out -- what went wrong! We followed all of the steps when doing the migration, especially making sure the collation of 'SQL_Latin1_General_CP437_CI_AI' was selected so that things would be encoded properly and case-insensitive.
I'm really at a loss as to where to begin checking for the cause of the problem. I tried searching for a similar issue but only found some vague similarities in JIRA 2.3 -- nothing in a recent version.
Any ideas? I even tried issuing a request directly to:
/rest/api/1.0/users/picker?query=d&showAvatar=true&_=1319429713276
And still got no results :-(
We've got our users synchronized (read-only) via LDAP, and our users screen shows we have 21780 total users (big organization), but only 19 are active (this is intentional). Again, this worked fine before migration.
Edit: We ran SQL Server Profiler to monitor what T-SQL the website was running to do the autocomplete, but as far as we could tell, the autocomplete action triggered no stored procedures and no T-SQL statements. So, basically, the autocomplete isn't even hitting our database?
