Error when loading certificates : path no resolved correctly

Hi,

My WordPress is hosted on an Azure Website.
I have configured the extension for using Azure AD. After enabled SSO, I can’t log in due to the following error :

Fatal error: Uncaught exception ‘SimpleSAML_Error_UnserializableException’ with message ‘Unable to load private key from file “D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\saml/cert/D:\home\site\wwwroot/wp-content/uploads/saml-20-single-sign-on/etc/certs/1/1.key”‘ in D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\saml\lib\SimpleSAML\Auth\Default.php:62 Stack trace: #0 D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\saml\lib\SimpleSAML\Auth\Simple.php(137): SimpleSAML_Auth_Default::initLogin(‘1’, ‘https://www.mat…’, NULL, Array) #1 D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\saml\lib\SimpleSAML\Auth\Simple.php(80): SimpleSAML_Auth_Simple->login(Array) #2 D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\lib\classes\saml_client.php(51): SimpleSAML_Auth_Simple->requireAuth(Array) #3 [internal function]: SAML_Client->authenticate(NULL) #4 D:\home\site\wwwroot\wp-includes\plugin.php(580): call_user_func_array(Array, Array) #5 D:\home\site\wwwroo in D:\home\site\wwwroot\wp-content\plugins\saml-20-single-sign-on\saml\lib\SimpleSAML\Auth\Default.php on line 62

The path to the certificate (and the key) is not resolved correctly. I try to debug the extension, but I can’t find where this value is set.

Is this error occurred to someone else ?
Is there a workaround or a fix ?

Thanks in advance for your reply ??
Best regards,
Matthieu
