sssd, kerberos,AD mixed case login names

For reasons unknown, any mixed case letter login (for example JamesBond) is no longer allowed access to a LINUX host. Yes, it used to work, but now it does not. In the past this issue was dealt with the presence of the following entry in the /etc/sssd/sssd.conf file:

case_sensitive = False

Today, someone discovered that if this line is removed the ability for the mixed case logins returns!

Ansible to the rescue!

A new group (named scom) containing the appropriate hosts is entered into the file /etc/ansible/hosts and followed with this two “statements”

# ansible -a "sed -i -e '/case_sensitive = False/d' /etc/sssd/sssd.conf" scom

# ansible -a "service sssd restart" scom

A few hours of work compressed into a minute or two – thanks Ansible!
