I finally got everything working, Except user manager gives this error.
The "UserManager" Web Part appears to be causing a problem. Negating the minimum value of a twos complement number is invalid.
Any ideas? thanks

After some research, here is what specifically causes the problem. The post from KnightOfNi at this thread: http://forums.msdn.microsoft.com/en-US/sharepointcollaboration/thread/e1f30852-8d60-4530-98b1-1151e3e30add/ is fundamentally correct, however, as in my client’s case, even after setting ADAM back on to the domain password policy, the same error still happens. The cause is that either no password expiration policy has been set or the policy is that the password does not expire. In Active Directory, this means setting the Password Expiration to 0 days. Definitely not a Microsoft best practice, but something mandated by my client’s senior management. The web part will work once the password expiration has been set. AD Password policy can only set at the domain level. You can set it elsewhere but it’s not going to have any (or in the case of computers...machine settings, little) effect. The ECTS looks for the first domain policy and checks its settings. That’s why if no Domain password expiration policy has been set or set to 0 days it will fail with the error message shown in the previous postings.
I hope this helps,

I have been recieving this error as well. It happens when I put the Manage External Users web part (from the External Collaberation Toolkit) on a page. It works fine until you add the first user. That's when this error occurs. Here is the full error message (with debugging set to true):

Basically Group Policy permission options fixed this instance.I had found the post and did what KnightOfNi did in the end which was to turn the Password policy back on. I had turned it off. I still came up with the same exception. I went ahead and uninstalled ADAM and then re-installed it with the ECTS script (twice). The same error is still happening. I've even undeploysolution (undeploysolution.cmd) the ECTS and uninstalled ADAM then reinstalled, but still have the same issue. All the ADAM reinstallations left the instance out of the box with the exception of setting the Administrator role as outlined in the directions for ECTS. So I'm still hunting down what in my configuration is not allowing the Manage External User web part from working.
Thanks,

Thanks for your replies to this, all the discussion is very helpful to me. I Hope this wiil be helpful to others.
When I received this error I had set up sharepoint services and ETCS on a server on the inside of my firewall and joined to the domain. The server had two network cards and two I.P's, one internal and one external. I then used a static from a global address directing ssl traffic to the external address. added the external name to my host file. It seemed that ETCS or windows did not like this scheme as DNS showed two host names on the same address. I then set up a linux box with IPCop as a firewall, put Sharepoint/ETCS with SQLServer and Adam in the DMZ. Opened a number of ports so I could join the domain and access active directory. Everything works like it should in this setup. Just to verify I had not made a mistake in my first 50 attemts I tested my static redirection scheme again matching everything in ETCS and IIS from the working setup . Again I got an error with the UserManager. The ETCS instructions recommend placing setup on the DMZ and this is how it all worked for me. Now if I can apply this to my PIX rather than IPCop life will be good..Dennis

- Hi,
sorry for kicking this one up. Is there a way to set a correct password policy if you aren't able to change the domains policy? I only have admin access to the ADAM server, not to the entire domain, so there's no way I can alter the domain policy. Can I force ADAM to use another policy somehow, or stop the server from inheriting the default domain policy?
Thanks,
Jasper
MCTS in Web Application Development in .NET 2.0 - No one? It's the only little thing I still have to fix. Please help me out guys :)
MCTS in Web Application Development in .NET 2.0 The solution for this problem (in code) is posted here: http://cks.codeplex.com/Thread/View.aspx?ThreadId=53465&ANCHOR#Post179970. Unfortunately I've been unable to get the webpart working with the code issue resolved. For some reason I can't get the public key token to match the one used by the installation. Has anyone got a clue on how to fix such an issue?
