Hello,
i have the same problem.
My Configuration:
Server:
Alfresco 3.2 Community Edition,
Authentication against LDAP/Active Directory, passthru for CIFS,
i can connect to Alfresco over WebDav and CIFS in Winodws Explorer.
Client:
Office 2003,
alfresco-community-office2003-addins-3.2
A few month ago, i installed alfresco-labs-word2003-addin-3a.1032 and could login succesfully.
The error message also appeard with this add-in, but when i clicked cancel, i could use i without problems.
Did you solve this problem? Or is this a bug?
