Hi all,
I just set up a Lync 2010 Server and tried to connect. Every client gets a pop up "Credentials required" window. Even if the login data is correct, it appears again if you hit the ok button.
The Configuration Information says that the GAL cannot "synchronize with the corporate address book. This may be because the proxy server setting in your web browser does not allow access to the address book. If the problem continues, please contact your support team". Also non of the clients gets a GalContacs.db in the personal folder.
I tried the CmdLets (New-CsAddressBookConfiguration), setup Kerberos accounts or the NTLM authentification. Also the certificate is correct and valid.
How can this problem be solved?
