Hello @meenasekar,

Thank you for the report! We are looking into this now and will work on a fix if any adjustments are needed in the plugin code.

We appreciate your patience while we get this sorted.

Hi @sentrypress, thank you for the update.
Would you mind first confirming that you have added the following filter? Without it set up, the problem will persist.

readme.txt
If you’re using the OneLogin connection type and need to modify the internal_config (e.g. to set requestedAuthnContext to false), you can use the wp_saml_auth_internal_config filter:

/**
 * Modify the OneLogin SAML configuration.
 */
add_filter( 'wp_saml_auth_internal_config', function( $config ) {
    $config['security'] = array(
        'requestedAuthnContext' => false,
    );
    return $config;
} );

Hopefully, this should be enough to fix the sso error.

Hi @shonu,
The functions wpsa_filter_option and wp_saml_auth_internal_config should be added to a custom mu-plugin (must-use plugin) to prevent them from being overwritten during updates. Alternatively, you can add these filters to your theme’s functions.php file, though they would also be at risk of being overwritten if the theme updates. While they could be added directly to our plugin files, they would be lost during our next plugin update.

The connection type is a matter of preference:

• OneLogin: This library is bundled with the plugin, configured via WordPress filters or the Settings page. This is the recommended one.
• SimpleSAMLphp: Requires a separate Composer installation and manual configuration files.

In your case, the RequestAuth issue can be resolved by adding the wp_saml_auth_internal_config filter to a mu-plugin (or similar). Just ensure it loads before our plugin to take full effect. This filter only works when connection_type is set to ‘internal’.

I apologize for any confusion, and I hope I’m not over-explaining or missing your point. We have updated the README to clarify these configuration steps. If you have any further questions, please let us know!

Example: Create /wp-content/mu-plugins/wp-saml-auth-config.php with:

<?php
// Set connection type to internal (bundled OneLogin library)
add_filter( 'wp_saml_auth_option', function( $value, $option_name ) {
if ( 'connection_type' === $option_name ) {
return 'internal';
}
return $value;
}, 10, 2 );

// Fix Azure AD requestedAuthnContext issue
add_filter( 'wp_saml_auth_internal_config', function( $config ) {
$config['security']['requestedAuthnContext'] = false;
return $config;
} );

Hi @shonu, @tekfused, the new release is addressing this issue as mentioned above.
Let us know if this improves your experience with the plugin.

Hi @meenasekar, the update has just been released. The log should be gone now. Let us know if anything arises.

Hello, we will be releasing it in the next few days. Thank you for your patience.
