[meta-freescale] after upgrade to fido proftpd fails to login using known good user/pass

[david at plentovichdesign.com]

I have a strange auth issue using normal unix user/pass login.  After
upgrading from dizzy to fido, proftpd (1.3.5) no longer allows a valid
user login (530 login incorrect).  SSH login does work correctly using the
same username and password.  Below I have listed the message log showing
successfile ssh login and failure of proftpd login.

I added auth trace logging into proftpd but it only shows that the user
password was not authenticated.

Has anyone run across this type of auth issue for fido?  Are there some
other system logs that could point to why the mod_auth_unix.c module is
rejecting a valid user/pass combination.  The user was created by root
using the "adduser" command, has a valid shell in the passwd file and is
not a member of any group.  Any help would be greatly appreciated.

BTW: If I cannot find a solution, is it possible to use a recipe file from
dizzy to build an older version of proftpd (1.3.4b) in fido?  I tried
copying the old proftpd recipe dir into fido but bitbake always built the
new (1.3.5) version of proftpd.  If you could point me to an example that
would be great.
