Subject: [PATCH] This fixes a regression in how random host-add OTP password
are generated. Some shells try and interpret certain special characters when
they confront them in unattended ipa-client-install where the OTP is used.
Before 4.5.0, this was fixed by excluding an arbitrary list of special
characters during OTP random password generation. This fix goes a step
further and removes ALL special characters when the OTP is generated. In my
opinion, the period of time between random OTP generation and use is small
and the password is useless after the host is installed so removing special
characters presents minimal security risk
