Yes, tomcat didn't have permission to expand the modules. It's working now.

Now I have a bigger question. We have a need to use ldap authentication, but it's not via an email address. However, Labkey users appear to be intimately tied to using the email address as the principle. Lookups of users uses the email, all the authentication calls use the email and verify it as email.

To add a new principle field in place of email and make email a regular field of a User appears to be a major change to some core stuff. I'm looking for advice - have there been thoughts of disentangling login from email? I do not want a customized Labkey installation here that I have to always keep merging with the latest Labkey releases. I'd like to make a patch/modification that Labkey.com can be happy with.
