Active Directory authentication for Linux

Add the following lines to your kickstart config.

# Join AD domain
yum -y install pbis-open
/usr/bin/domainjoin-cli setname ${hostname}.corp.yourdomain.com
/usr/bin/domainjoin-cli join --ou OU=LinuxServers,OU=Internal,DC=corp,DC=yourdomain,DC=com corp.yourdomain.com joinaccount joinpassword
/opt/pbis/bin/config AssumeDefaultDomain true
/opt/pbis/bin/config LoginShellTemplate /bin/bash
/opt/pbis/bin/config HomeDirTemplate %H/%D/%U


Simple shell script to do the same:
joinad.sh

#!/bin/bash
if [ -z "$1" ]
  then
    echo "Usage: joinad.sh yourservername"
    exit 1
fi

echo "Joining $1"
ssh -t $1 "domainjoin-cli join --disable hostname --ou OU=LinuxServers,OU=Internal,DC=corp,DC=yourdomain,DC=com corp.yourdomain.com joinaccount joinpassword; /opt/pbis/bin/config AssumeDefaultDomain true; /opt/pbis/bin/config LoginShellTemplate /bin/bash; /opt/pbis/bin/config HomeDirTemplate %H/%U"
