Duration Notation Format
We have implemented a string/integer based notation for configuration options that take a duration of time. This section describes the implementation of this. You can use this implementation in various areas of configuration such as:
- session:
- expiration
- inactivity
- remember_me
- regulation:
- ban_time
- find_time
- ntp:
- max_desync
- webauthn:
- timeout
The way this format works is you can either configure an integer or a string in the specific configuration areas. If you
supply an integer, it is considered a representation of seconds. If you supply a string, it parses the string in blocks
of quantities and units (number followed by a unit letter). For example 5h indicates a quantity of 5 units of h.
The following is ignored:
- all spaces
- leading zeros
While you can use multiple of these blocks in combination, we suggest keeping it simple and use a single value.
Unit Legend
Short Units
These values have been available for a long time.
| Unit | Associated Letter |
|---|---|
| Years | y |
| Months | M |
| Weeks | w |
| Days | d |
| Hours | h |
| Minutes | m |
| Seconds | s |
Long Units
These values are more human readable but have only been available since v4.38.0.
| Unit | Human Readable Long Unit |
|---|---|
| Years | year, years |
| Months | month, months |
| Weeks | week, weeks |
| Days | day, days |
| Hours | hour, hours |
| Minutes | minute, minutes |
| Seconds | second, seconds |
| Milliseconds | millisecond, milliseconds |
Examples
| Desired Value | Configuration Examples |
|---|---|
| 1 hour and 30 minutes | 90m or 1h30m or 5400 or 5400s |
| 1 day | 1d or 24h or 86400 or 86400s |
| 10 hours | 10h or 600m or 9h60m or 36000 |
Address
The address type is a string that takes the following format:
[<scheme>://]<ip>[:<port>]
The square brackets indicate optional sections, and the angled brackets indicate required sections. The following sections elaborate on this. Sections may only be optional for the purposes of parsing, there may be a configuration requirement that one of these is provided.
scheme
The entire scheme is optional, but if the scheme host delimiter :// is in the string, the scheme must be present. The
scheme must be one of tcp://, or udp://. The default scheme is tcp://.
ip
The IP is required. If specifying an IPv6 it should be wrapped in square brackets. For example for the IPv6 address
::1 with the tcp:// scheme and port 80: tcp://[::1]:80.
port
The entire port is optional, but if the host port delimiter : exists it must also include a numeric port.
Regular Expressions
We have several sections of configuration that utilize regular expressions. It's recommended to validate your regex
manually either via tools like Regex 101 (ensure you pick the Golang option) or some other
means.
It's important when attempting to utilize a backslash that it's utilized correctly. The YAML parser is likely to parse this as you trying to use YAML escape syntax instead of regex escape syntax. To avoid this use single quotes instead of no quotes or double quotes.
Good Example:
domain_regex: '^(admin|secure)\.example\.com$'
Bad Example:
domain_regex: "^(admin|secure)\.example\.com$"
TLS Configuration
Various sections of the configuration use a uniform configuration section called TLS. Notably LDAP and SMTP. This section documents the usage.
server_name
{{< confkey type="string" required="no" >}}
The key server_name overrides the name checked against the certificate in the verification process. Useful if you
require an IP address for the host of the backend service but want to verify a specific certificate server name.
skip_verify
{{< confkey type="boolean" default="false" required="no" >}}
The key 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
{{< confkey type="string" default="TLS1.2" required="no" >}}
Controls the minimum TLS version Authelia will use when performing TLS handshakes.
The possible values are TLS1.3, TLS1.2, TLS1.1, TLS1.0, SSL3.0. Anything other than TLS1.3 or TLS1.2
are very old and deprecated. You should avoid using these and upgrade your backend service instead of decreasing
this value. At the time of this writing SSL3.0 will always produce errors.
maximum_version
{{< confkey type="string" default="TLS1.3" required="no" >}}
Controls the maximum TLS version Authelia will use when performing TLS handshakes.
The possible values are TLS1.3, TLS1.2, TLS1.1, TLS1.0, SSL3.0. Anything other than TLS1.3 or TLS1.2
are very old and deprecated. You should avoid using these and upgrade your backend service instead of decreasing
this value. At the time of this writing SSL3.0 will always produce errors.
certificate_chain
{{< confkey type="string" required="no" >}}
The certificate chain/bundle to be used with the private_key to perform mutual TLS authentication with the server.
The value must be one or more certificates encoded in the DER base64 (RFC4648) encoded PEM format.
private_key
{{< confkey type="string" required="no" >}}
Important Note: This can also be defined using a secret which is strongly recommended especially for containerized deployments.
The private key to be used with the certificate_chain for mutual TLS authentication.
The value must be one private key encoded in the DER base64 (RFC4648) encoded PEM format. If more than one certificate is provided, in top down order, each certificate must be signed by the next certificate if provided.
Server Buffers
read
{{< confkey type="integer" default="4096" required="no" >}}
Configures the maximum request size. The default of 4096 is generally sufficient for most use cases.
write
{{< confkey type="integer" default="4096" required="no" >}}
Configures the maximum response size. The default of 4096 is generally sufficient for most use cases.
Server Timeouts
read
{{< confkey type="duration" default="6s" required="no" >}}
Note: This setting uses the duration notation format. Please see the common options documentation for information on this format.
Configures the server read timeout.
write
{{< confkey type="duration" default="6s" required="no" >}}
Note: This setting uses the duration notation format. Please see the common options documentation for information on this format.
Configures the server write timeout.
idle
{{< confkey type="duration" default="30s" required="no" >}}
Note: This setting uses the duration notation format. Please see the common options documentation for information on this format.
Configures the server idle timeout.
