Sorry, that username already exists! Error after first login attempt
rfair404 opened this issue · 3 comments
I have installed the plugin and coordinated the metadata with my SAML provider. Everything seems to be working as expected, however when I attempt to log in for a second time I get an error: Sorry, that username already exists!
Any idea how this can be resolved?
I'm experiencing the same issue on a multi site instance. Users were able to sign in and then on a second attempt Sorry, that username already exists!
continues to show up.
Looks like on my end it was an issue with a username being used as the NameID while not being an actual email address.

We had this issue as well because our current site was not using email address for the user logins. so i changed the logic to be
if ( $is_email_auth ) {
$email = filter_var( $saml->getNameId(), FILTER_VALIDATE_EMAIL );
} else {
$email_field = $map['user_email'];
$email = current( (array) $saml->getAttribute( $email_field ) );
}
if(!$email)
{
//fix for not being able to find the email address
$email = isset( $map['user_email'], $attributes[ $map['user_email'] ] ) && is_array( $attributes[ $map['user_email'] ] ) ? reset( $attributes[ $map['user_email'] ] ) : '';
}
