https://bugzilla.samba.org/show_bug.cgi?id=15480 --- Comment #8 from Steve French <sfrench@xxxxxxxxx> --- The trace you sent shows an access denied on SMB3.1.1 session setup (NTLMv2/NTLMSSP not Kerberos). The username looks plausible (based on the netname context sent, it matches that), but the obvious question is the password (either the one stored in your credentials file or passed on mount depending on how you mount this). You can also verify that the credentials are ok by using smbclient //server/share -U username%password If that also fails then access to the network may be disabled from some subnets so best to contact Azure support since they can look at the storage account and networking configuration. -- You are receiving this mail because: You are the QA Contact for the bug.
