We only have WSS 2.0 and we are having problems with users belonging to AD
groups gettig access to sites if the AD group name has a '-' in it. For example,
we have a group EB-Sharepoint-Test1 and I add the user to that group and add the
group to a Sharepoint site. The user gets prompted for credentials. I then add
the user to EB_XA08_WSS and add that group to the site and they can get in fine.

Is this a known issue? If so, can someone point me to the documentation? I need
it as our company has a policy to only use dashes in AD Group names.
