Hello. I have IPA domain with AD integration. Also there is samba share on ipa member. All works fine, but now i want to scan from my network MFP to samba share. I tried all settings, but always had Incorrect credentials. Check your username/password and try again.   Any ideas? I think MFP doesnt know about kerberos. Attached some share settings from MFP. P.S.: yes, i have acces with this credentials from linux and windows.

Did you try an smbclient access with these credentials? Does it use NTLMSSP? If you'd force NTLMSSP instead of Kerberos, does it work?

What OS are you using for that IPA client?
