Authentication guide - SAML
|
|
===
|
|
|
|
**Note:** *This guide was written before the renaming. Just replace `HackMD` with `CodiMD` in your mind :smile: thanks!*
|
|
|
|
The basic procedure is the same as the case of OneLogin which is mentioned in [OneLogin-Guide](./saml-onelogin.md). If you want to match your IdP, you can use more configurations as below.
|
|
|
|
* If your IdP accepts metadata XML of the service provider to ease configuration, use this url to download metadata XML.
|
|
* {{your-serverurl}}/auth/saml/metadata
|
|
* _Note: If not accessible from IdP, download to local once and upload to IdP._
|
|
* Change the value of `issuer`, `identifierFormat` to match your IdP.
|
|
* `issuer`: A unique id to identify the application to the IdP, which is the base URL of your CodiMD as default
|
|
* `identifierFormat`: A format of unique id to identify the user of IdP, which is the format based on email address as default. It is recommend that you use as below.
|
|
* urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress (default)
|
|
* urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
|
|
* `config.json`:
|
|
```javascript
|
|
{
|
|
"production": {
|
|
"saml": {
|
|
/* omitted */
|
|
"issuer": "mycodimd"
|
|
"identifierFormat": "urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
* environment variables
|
|
```
|
|
CMD_SAML_ISSUER=mycodimd
|
|
CMD_SAML_IDENTIFIERFORMAT=urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
|
|
```
|
|
|
|
* Change mapping of attribute names to customize the displaying user name and email address to match your IdP.
|
|
* `attribute`: A dictionary to map attribute names
|
|
* `attribute.id`: A primary key of user table for your CodiMD
|
|
* `attribute.username`: Attribute name of displaying user name on CodiMD
|
|
* `attribute.email`: Attribute name of email address, which will be also used for Gravatar
|
|
* _Note: Default value of all attributes is NameID of SAML response, which is email address if `identifierFormat` is default._
|
|
* `config.json`:
|
|
```javascript
|
|
{
|
|
"production": {
|
|
"saml": {
|
|
/* omitted */
|
|
"attribute": {
|
|
"id": "sAMAccountName",
|
|
"username": "displayName",
|
|
"email": "mail"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
* environment variables
|
|
```sh
|
|
CMD_SAML_ATTRIBUTE_ID=sAMAccountName
|
|
CMD_SAML_ATTRIBUTE_USERNAME=nickName
|
|
CMD_SAML_ATTRIBUTE_EMAIL=mail
|
|
```
|
|
|
|
* If you want to control permission by group membership, add group attribute name and required group (allowed) or external group (not allowed).
|
|
* `groupAttribute`: An attribute name of group membership
|
|
* `requiredGroups`: Group names array for allowed access to CodiMD. Use vertical bar to separate for environment variables.
|
|
* `externalGroups`: Group names array for not allowed access to CodiMD. Use vertical bar to separate for environment variables.
|
|
* _Note: Evaluates `externalGroups` first_
|
|
* `config.json`:
|
|
```javascript
|
|
{
|
|
"production": {
|
|
"saml": {
|
|
/* omitted */
|
|
"groupAttribute": "memberOf",
|
|
"requiredGroups": [ "codimd-users", "board-members" ],
|
|
"externalGroups": [ "temporary-staff" ]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
* environment variables
|
|
```sh
|
|
CMD_SAML_GROUPATTRIBUTE=memberOf
|
|
CMD_SAML_REQUIREDGROUPS=codimd-users|board-members
|
|
CMD_SAML_EXTERNALGROUPS=temporary-staff
|
|
```
