Hi guys,
Diging a 6 years old subject from the grave.
I installed centrifiy on Ubuntu 16.04 for R&D prupose.
I getting the same issue, my user cant access Windows shared directorie without the password promt.
I'm still surprising to find a post related to this after 6 years O.o did i miss something ?
Anyway, did you have a solution or maybe a more kerberos friendly file explorer to try ?
