Is this even going to work? We have had this problem for many days now and trying to solve it and starts wondering if this is how it is suppose to work or if I'm on a completely wrong track here.
I got a possible answer from a colleague of mine. This is a bug in EPiServer's ActiveDirectoryRoleProvider that causes to just show the first 1000 groups and not all of them.
Can any EPiServer employee confirm this?
I have the same issue in CMS 5 R2
I used a custom made provider that a colleague of mine have written to avoid the problem. I suggest you write a custom also. I don't have the code here so I can't help you anymore.
Yes there is a limitation in the AD provider. Please read Daniel Berg's post about as he tells you about another limitation (and how to get around it):
I have a problem getting all the groups showing when I try to set access to certain groups. I have an AD connection to a AD 2008 and the server is a Windows 2008 Server R2.
I haven't found any thing that is different between the groups that are showing and the groups that are not showing. I'm using the ActiveDirectoryRole/MembershipProvider.
