I am experiencing both of these exact problems on a Moto G. Were solutions to either or both of these problems found?
I think it is a problem of file-permissions on MOTOs
here my solution (just testing):
set permissions to 755 (eg. with root browser)
for smb.conf to 755 the password-error is gone
but sfs does not start so I set com.funkyfesh.samba and alle files in it (for testing) to 755
and it works :laugh:
to share your 2nd scdard:
copy all lines of [sdcard] ff..
as new entry on bottom of smb.conf
and change [sdcard] to [sdcard1]
and path-line to your-path-of-sdcard1
