We have been using Akamai EAA which is a SDP and similar to VPN. We let our users use our onsite netapp CIFS file share via EAA.
But something weird is happening, when connecting via FQDN, copying any file to the local PC just STOPS. When connecting via NetBios name and IP address it seems to be fine. Also when doing the same procedure using a Windows File Server its fine on all 3.
I looked at the SMB session when these things are happening and, when copying fails, there is only 2 kerberos authentication session to the destication file share and when its working fine, there is 2 kerberos session and 1 NTLMv2 authentication session.
Has anyone come across something like this? if so if anyone can guide me to a solution that would be more than appreciated.
1) "secd.log" file located in the /etc/log directory accessible via the SPI interface.
2) From a Domain joined machine or a DC, run the command 'setspn.exe -l CIFSFILERNAME' (this is view only, despite the command saying 'set') from the cmd CLI, to have the server display all the entries related to the SPN for the hostname.
