      <description>by Meg Sum. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;The issue arises from Moodle 4.3.2 no longer allowing NULL passwords in the database. Since SSO bypasses password creation for new users, the plugin needs an update to reflect this change. For now, I'm using a placeholder password as a workaround. Gopal Sharma, please kindly update the plugin. &lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by KATERYNA MARTYNENKO. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;I ran into the problem of duplicating users when previously existing users switched to this auth plugin. &lt;br&gt;
&lt;br&gt;
I modified the plugin to match users by email address and this prevented the duplicated users problem.&lt;br&gt;
&lt;br&gt;
Feel free to use my patched version here:&lt;br&gt;
