[Freeipa-users] Ubuntu Samba Server Auth against IPA

Hi Youenn,

OK thanks! this takes me a little but futher now and I see some good
stuff in my logging.

I'm testing on a Windows 10 Machine which is not member of an AD or
so, so that might be my issue for now ?

When testing on the samba box itself as my user I get:


[myusername at smb-01 ~]$ smbclient //smb-01.domain.local/shares

...
Checking NTLMSSP password for MSP\myusername failed: NT_STATUS_WRONG_PASSWORD
...
SPNEGO login failed: NT_STATUS_WRONG_PASSWORD


Maybe I have an issue with encrypted passwords ?


When we have this all working, I think we have a howto :D

Thanks!

Matt
