Ok I got around the problem of /bin/false shell ! I rechecked all the configs
and joined the machines to to domain again using
net join ads -w asurite -U Administrator -S <server-name>
and it showed proper login shell in getent output! So users can login now, and
thanks to Philipoff's excellent suggestion, I have given ssh access only to
admins group using pam_succeed_if.so
Only issue now is , intermittently winbind seems to die and getent produces no
output , and users cannot login , the /var/log/secure entries are
Jun 5 16:06:24 mymachine sshd: pam_winbind(sshd:account):
pam_winbind_request: read from socket failed!
Jun 5 16:06:24 mymachine sshd: pam_winbind(sshd:account): internal
module error (retval = 3, user = 'abhinan')
Jun 5 16:06:24 mymachine sshd: Failed password for abhinan from
22.214.171.124 port 50991 ssh2
Jun 5 16:06:24 mymachine sshd: fatal: Access denied for user abhinan
by PAM account configuration
A restart of winbind service fixes this problem. Also during this, the
winbindd log shows error regarding DCERPC_FAULT_ACCESS_DENIED .
So thanks to all here, apart from this issue my original problem is solved
