radicale-bsdauth 1.0.1

Login to Radicale with your native OpenBSD accounts.

OpenBSD Authentication plugin for Radicale

This connects a radicale install to the local OpenBSD's authenticate(3) system that it is installed on. It means you can access your calendars with the same password you use for ssh and, perhaps, email, chat, etc.

Installation

This has only been tested against radicale>=3, which is not yet packaged for OpenBSD, so you must install that version manually (below) if it's not already.

Then install the plugin:

doas pip install radicale-bsdauth

In order to function, you also need to grant radicale access to authenticate(3):

usermod -G auth _radicale

And then tell radicale to use it by editing /etc/radicale/config or /var/lib/radicale/.config/radicale/config to add

[auth]
type = radicale_bsdauth

Install Radicale 3 on OpenBSD

If you are currently using version 2, you should backup your calendars before proceeding because upgrading risks breaking something. It's unlikely, but possible.

doas -u _radicale tar -jcvf - /var/lib/radicale/collections | (umask 027; cat > radicale-collections.tgz) # for example

Then install radicale 3:

doas pkg_add python3
doas pip install --upgrade pip
doas pip install "radicale>=3"

# Set up radicale's environment
# ( these rest of these steps would normally be handled by pkg_add(1) )
doas useradd -d /var/lib/radicale -m -L daemon -r 1..999 _radicale # if you don't already have this user
cat <<EOF | doas tee /etc/rc.d/radicale && doas chmod +x /etc/rc.d/radicale
#!/bin/ksh

daemon="/usr/local/bin/radicale"
daemon_user="_radicale"
daemon_logger="daemon.info"

. /etc/rc.d/rc.subr

rc_start() {
        \${rcexec} "\${daemon_logger:+set -o pipefail; }\${daemon} \${daemon_flags}\${daemon_logger:+ 2>&1 |
                logger -ip \${daemon_logger} -t \${_name}} \&"
}

# Beware: you need to update this for to the python you actually have installed
pexp="/usr/local/bin/python3.8 /usr/local/bin/radicale"

rc_cmd \$1
EOF
doas rcctl enable radicale
doas rcctl start radicale

• radicale-auth-PAM:

  OpenBSD's authenticate(3) is like Linux's PAM(8): a way to enable multiple ways to prove your identity, from passwords to LDAP to YubiKeys.

  So radicale-auth-PAM provides the same basic feature to radicale as radicale-bsdauth, and if you're using Linux you should use it.
