I have run into an issue trying to map a network drive from a Windows Server 2012R2 to a test UCS server. The UCS server is at the latest version of of today (4.4-4 errata617).
The issue appears to be the authentication method used by the Windows Server against the Samba server. If I manually edit the [global] section in the /etc/samba/smb.conf file from:
ntlm auth = ntlmv2-only
ntlm auth = yes
the Windows server will connect and map the drive. Otherwise, it reports “The username or password is incorrect.” Testing from a Debian 10 client without the change has no issues. Also no problem from a Windows 10 1909 machine.
The manual edit is not really a fix, though, because the change gets overwritten by many other operations in UCS. Is there a proper way to fix this issue?
