Hi guys, Thank you so much your previous answers. I realised my SID were stored in ipaNTsecurityidentifier, thanks to ipa-adtrust-install --add-sids
I found an other way to configure smb here: http://freeipa-users.redhat.narkive.com/ez2uKpFS/authenticate-samba-3-or-4-with-freeipa It works perfectly. I'm using module ipasam.so I have manually scp to the samba server, Samba is set to use kerberos + ldapsam via this ipasam module. Following the instructions, I created a user role allowing service principal to read ipaNTHash value from the LDAP. ipaNTHash are generated each time a user changes his password. Authentication works perfectly on Windows 7, 8 and 10. For more details, the previously linked thread is quite clear.
