First LDAP encounter

I have started to learn LDAP today. Here is how I did it:

  • Install new Red Hat Linux 7.2 server.
  • During install
    • Specify to authenticate through LDAP which is located at 127.0.0.1
    • I forgot to permit SSH connection during firewall configuration
    • In boot manager configuration, I have specified to use GRUB with which I don’t have any experience yet.

When I did all this, I have found myself in situation where machine refused any connections via secure shell, refused any logins locally, Result:

  1. Unusable machine
  2. Frozen butt (a/c in the server room)
  3. Complete reinstall
  4. Linux LDAP Tutorial
