samba start error
smbd: relocation error: /lib/libsamba-credentials.so.0: symbol GSS_KRB5_CRED_NO_CI_FLAGS_X, version gssapi_krb5_2_MIT not defined in file libgssapi_krb5.so.2 with link time reference
Package krb5-libs-1.13.2-11.fc23.i686 is already installed
should update krb5-libs-1.13.2 to krb5-libs-1.14.1
so: sudo dnf install krb5-libs-1.14.1-*

or smbd would not start properly (error exit)
