Authelia uses a YAML file as configuration file. A template with all possible options can be found here, at the root of the repository.
When running Authelia, you can specify your configuration by passing the file path as shown below.
$ authelia --config config.custom.yml
We document the configuration in two ways:
The configuration yaml default has comments documenting it. All documentation lines start with
##. Lines starting with a single
#are yaml configuration options which are commented to disable them or as examples.
This documentation site. Generally each section of the configuration is in its own section of the documentation site. Each configuration option is listed in its relevant section as a heading, under that heading generally are two or three colored labels.
typelabel is purple and indicates the yaml value type of the variable. It optionally includes some additional information in parentheses.
defaultlabel is blue and indicates the default value if you don’t define the option at all. This is not the same value as you will see in the examples in all instances, it is the value set when blank or undefined.
requiredlabel changes color. When required it will be red, when not required it will be green, when the required state depends on another configuration value it is yellow.
Authelia validates the configuration when it starts. This process checks multiple factors including configuration keys that don’t exist, configuration keys that have changed, the values of the keys are valid, and that a configuration key isn’t supplied at the same time as a secret for the same configuration option.
You may also optionally validate your configuration against this validation process manually by using the validate-config option with the Authelia binary as shown below. Keep in mind if you’re using secrets you will have to manually provide these if you don’t want to get certain validation errors (specifically requesting you provide one of the secret values). You can choose to ignore them if you know what you’re doing. This command is useful prior to upgrading to prevent configuration changes from impacting downtime in an upgrade. This process does not validate integrations, it only checks that your configuration syntax is valid.
$ authelia validate-config configuration.yml
We have implemented a string based notation for configuration options that take a duration. This section describes its usage. You can use this implementation in: session for expiration, inactivity, and remember_me_duration; and regulation for ban_time, and find_time. This notation also supports just providing the number of seconds instead.
The notation is comprised of a number which must be positive and not have leading zeros, followed by a letter denoting the unit of time measurement. The table below describes the units of time and the associated letter.
- 1 hour and 30 minutes: 90m
- 1 day: 1d
- 10 hours: 10h
Various sections of the configuration use a uniform configuration section called TLS. Notably LDAP and SMTP. This section documents the usage.
server_name overrides the name checked against the certificate in the verification process. Useful if you require to use a direct IP address for the address of the backend service but want to verify a specific SNI.
skip_verify completely negates validating the certificate of the backend service. This is not recommended, instead you should tweak the
server_name option, and the global option certificates_directory.
minimum_version controls the minimum TLS version Authelia will use when opening TLS connections. The possible values are
TLS1.0. Anything other than
TLS1.2 are very old and deprecated. You should avoid using these and upgrade your backend service instead of decreasing this value.
