KDM does not allow root login after installing the operating system

Problem

KDM does not allow root login after installing the operating system

Effected distributions

  • Fedora Core 3
  • Fedora Core 4
  • RHEL 4
  • CentOS 4

Solution

By default, the installer disables root logins via KDM. This behavior can be changed by editing /etc/kde/kdm/kdmrc and set the value of AllowRootLogin to true. Note there are two entries of AllowsRootLogin that must be changed.

Original Entry 

AllowRootLogin=false

New Entry 

AllowRootLogin=true

Then restart KDM by pressing Ctrl-Alt-Backspace.
