javascript: $('...').attr('checked')==true never neems to evaluate to TRUE
The checks of the form if ($('...').attr('checked')==true) { ... } never seem to trigger in my environment.
Ttest case: attributes exported to a SAML SP always get stored as non-mandatory.
Changing the checks to a simple if ($('...').attr('checked')) { ... } [i.e. removing the "==true" part] or alternatively if ($('...').attr('checked')=='checked') { ... } fixes the issue.
As it occurs with three JavaScript engines, I am pretty convinced, the issue is on the LemenLDAP-NG side.
Please check and consider integrating a fix into the next release of LemonLDAP-NG.
