The command written in authorized_keys for ssh publickey authentication is not executed.

Issue

• As written in man sshd, it's possible to specify the command variable in authorized_keys.
• The following command is specified, ssh login from a client hanged.

command="logger -p auth.info -t LOGIN 'new user logged in'; login -p -f root" ssh-rsa ....

• If the first logger command is removed, it works.
