FlexAuth: independent library for symfony security

Allows switching the UserProvider at Runtime using environment variables.

Dynamic UserProvider that supports multiple backends based on environment variables.

To override which should provider configuration as array for runtime FlexAuth\FlexAuthTypeProviderInterface

Using FlexAuth\FlexAuthTypeProviderFactory::fromEnv('FLEX_AUTH'') and define env variables in format type?param1=value1&param2=value2&param3=value3

Example define environment variable

## Use memory provider
FLEX_AUTH=memory?users=alice:4l1c3:ROLE_ADMIN;ROLE_EXAMPLE,bob:b0b:ROLE_EXAMPLE)
## Or use userbase provider
FLEX_AUTH=userbase?dsn=https://username:password@userbase.example.com
## Or use the entity provider
FLEX_AUTH=entity?class=\App\Entities\User&property=username
## Or use a JWT provider
FLEX_AUTH=jwt?algo=RS256&publickey=@\cert\public_key.key&private_key=@\cert\privite_key.key&userField=username&groupField=permissions

A long form format could be supported like this:

FLEX_AUTH=entity
FLEX_AUTH_ENTITY_CLASS=\App\Entities\User
FLEX_AUTH_ENTITY_PROPERTY=username

Dynamically flex type provider example.

class MyFlexAuthTypeProvider implements FlexAuthTypeProviderInterface {
    protected $className = \App\Entities\User::class; // can be change in runtime
    protected $propery = 'id';
    
    //...
    public function provide(): array { // will be call every time
        return [
            'type' => 'entity',
            'class' => $this->className,
            'propery' => $this->propery, // dynamic user identificator
        ];
    }
    
    public function switchToEmail() {
        $this->propery = 'email';
    }
}
