Have error setting APex 21.2 with SAML using Doc ID 2864182.1 from Oracle support

running

--------

openssl req -newkey rsa:2048 -nodes -x509 -days 365 -out cert.pem -keyout key.pem

what value for "Common Name (eg, your name or your server's hostname) []:login."?

I put Azure host: microsoftonline.com or should I put my server host full name ?

after I run

begin

apex_instance_admin.set_parameter('SAML_ENABLED', 'Y');

apex_instance_admin.set_parameter('SAML_APEX_CERTIFICATE','... contents of cert.pem ...');

apex_instance_admin.set_parameter('SAML_APEX_PRIVATE_KEY','... contents of key.pem ...');

end;

in part '... contents of cert.pem ...', I replace string from my cert.pem file (Removed -----BEGIN CERTIFICATE----- Removed -----END CERTIFICATE----- Removed newlines and other white space)
