I was able to just bring up a snapshot of the original server and then update but exclude the samba packages.

Hi everyone,

Yesterday I updated our (Centos 7) Freeipa servers and it seems that now the samba shares hosted on one of them is no longer accessible. I've done some reading and see that authentication now requires the winbind package to be running, and in our case it is, but I'm still not able to authenticate users on either Windows or Linux. We do not use AD so there are no trusts to worry about. Has anyone else experienced this and know a solution? 

Thanks,

Jeff
