If you are using Grails Spring Security in your application, one killer functionality that we can easily provide is a simple user switcher
\nAdd this to your admin layout:<\/p>\n

[html]
\n&lt;sec:ifAllGranted roles=’ROLE_ADMIN’&gt;
\n &lt;form action=’\/j_spring_security_switch_user’ method=’POST’&gt;
\n Switch: &lt;g:select from=&quot;${users}&quot; optionKey=&quot;username&quot; optionValue=&quot;displayInfo&quot;
\n name=’j_username’\/&gt;&amp;nbsp;&lt;input type=’submit’ value=’Switch’\/&gt;
\n &lt;\/form&gt;
\n&lt;\/sec:ifAllGranted&gt;
\n&lt;sec:ifSwitched&gt;
\n &lt;a href=’${request.contextPath}\/j_spring_security_exit_user’&gt;
\n Resume as &lt;sec:switchedUserOriginalUsername\/&gt;
\n &lt;\/a&gt;
\n&lt;\/sec:ifSwitched&gt;
\n[\/html]<\/p>\n

In Config.groovy, add the following:<\/p>\n

[groovy]grails.plugins.springsecurity.useSwitchUserFilter = true[\/groovy]<\/p>\n

So, in two easy steps we can provide the application admin to impersonate other users. This also checks if the current user is actually an impersonation and if it is, it provides a link to go back to the original user.<\/p>\n

Very neat indeed \ud83d\ude42<\/p>\n
