With the latest MLE installed on Moodle 1.9.10, I can access and login to the MLE web interface from my mobile phone successfully. However, when installing the mobile phone client (Nokia or generic version), I receive the following error:
"Your attempt to log in failed. Please check your settings and try again. If the problem persists, please contact your administrator."
Our installation has been performed as per the Step-by-Step Tutorial, default Download-Server enabled. This issue does not occur on the elibera.com demo site. Another user has reported the same issue on his MLE-Moodle deployment: https://sourceforge.net/apps/phpbb/mle/viewtopic.php?f=6&t=100.
I did detect that the MLE authentication plugin displays as [[auth_mletitle]] on the Manage authentication admin screen and is disabled after MLE installation. Enabling this plugin did however not resolve this issue. I can also see the failed login attempts in the Moodle live logs:
login failed for john
Please let me know if more information is required.
