vyos 1.2 openvpn client names with spaces created incorrectly
Open, Requires assessmentPublicBUG

Description

When setting an openvpn client with a name using the command

set interfaces openvpn vtun0 server client "John Smith" ip 10.190.1.1

the config is correctly set but the resulting user created in /opt/vyatta/etc/openvpn/ccd/vtun0/ is not created correctly. With the above command a file with the name John is created in /opt/vyatta/etc/openvpn/ccd/vtun0/ while a file name Smith is created in /home/vyos. In openvpn 2.3 and above, the client names no longer use the underscore to replace space or other special character and it expects the file name with the spaces and other special characters to be created for each user to match their client certificate CN. So a file with "John Smith" must be created in /opt/vyatta/etc/openvpn/ccd/vtun0/. This issue prevents any user whose name has spaces from being able to login to openvpn when the reject-unconfigured-clients option is set, as the name doesn't match. Since vyos 1,2 is uing openvpn 2.4, there is a temporary workaround for this by using openvpn-option '--compat-names' to force it to use the old naming convention of underscore instead of space. However, the --compat-names is deprecated and removed from openvpn 2.5. Below is the configurations causing the problem.

vyos@vyos# show interfaces openvpn
