I have a ASA5580 ( ASA version 8.1.1, ASDM version 6.1.3 ). I tried to access CIFS servers. After I passed CIFS server authentication and click any files or folders, it popup another one authentication windows, I must type CIFS server username and password again to access those files or folders. I have configure ASA5510 before, but never see that problem. Can you help me to resolve this problem?
