how can a user change password

[deleted]

I have OpenVPN access server using a standalone radius server to authenticate users.
Is there any way for the user to change the password?

Yeah, the user has to change his password in the RADIUS server - you'll have to find some tool that allows this. The Access Server just authenticates against RADIUS, it does not reach in and change user passwords, sorry.

If you have forgotten the password for this user on your OpenVPN Access Server you can reset the password for the “OpenVPN" user on the command line with password OpenVPN. Please note that you can not and should not use the “root" user credentials to log in at the Admin UI

Yes, you can change password using the terminal in linux. You need to ensure you don't use root privileges while changing the password. Try finding the correct command for changing password by typing man openvpn in the terminal. This would help.
Good luck.
