I already had template shell = /bin/bash in my smb.conf, and still winbind was
reporting the shell as /bin/false. This is the real problem. Winbind seems to
ignore the template shell directive from the config file!!! First I tried with
a manually edited file, next I configured using authconfig-gtk in fedora, both
give same results (ie shell reported as /bin/false. I am posting my current
smb.conf here.

# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.
