@zooney Yes, this fix only runs at account generation time. No reason why you shouldn’t update the database to fix the existing users.

…oh wait! They do ?? My bad

@mitcho, long time ago now, but I suspect I picked sanitize_title because of wp-includes/registration.php#L132.

I assume you mean sanitize_user, rather than sanitize_name? If this is the case then, I would agree that this is more appropriate than sanitize_title. Interesting that this method is not used in the core registration…

Zooney,

My solution is to add the filter I mentioned in my original post:
add_filter( 'shibboleth_user_nicename', 'sanitize_title');
You can either create a single plugin with this line, or, to keep it simple, you can just add it in the shibboleth.php code.

I’ve added mine just above
$shib_headers = shibboleth_get_option('shibboleth_headers');
inside the shibboleth_update_user_data function.

Hopefully this can be integrated into future releases.
