Full Discussion: Need to login without password using ssh
Operating Systems Linux Red Hat Need to login without password using ssh Post 302969613 by acascianelli on Thursday 24th of March 2016 02:59:27 PM

Add your public SSH key to the .ssh/authorized_keys file in the users home directory.

If you don't have an SSH key pair, generate one with ssh-keygen. If you give it a password while generating, you'll need to enter that password when logging in, so I'm guessing you'll want to leave that blank.

You also have to make sure permissions are set correctly on various files and folders:
  • Home dir: no more than 755 (not group or world writable).
  • .ssh dir: no more than 755 (not group or world writable). (mkdir -m755
  • authorized_keys file: not more than 644 (not group or world writable)
  • id_rsa.pub (Public key) file: not more than 644 (not group or world writeable)
  • id_rsa (Private key) file: not more than 600 (not group or world readable)

ssh-ldap-helper

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME

     ssh-ldap-helper -- sshd helper program for ldap support

SYNOPSIS

     ssh-ldap-helper [-devw] [-f file] [-s user]

DESCRIPTION

     ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP.  ssh-ldap-helper is disabled by default and can only be enabled in the
     sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.

     ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.

     The options are as follows:

     -d      Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.

     -e      Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.

     -f      ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).

     -s      ssh-ldap-helper prints out the user's keys to stdout and exits.

     -v      Implies -d; increases verbosity.

     -w      ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.

SEE ALSO

     sshd(8), sshd_config(5), ssh-ldap.conf(5),

HISTORY

     ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
