[SOLVED] SSO and iFrame issue (IE8)

[HervE]

Hello forum,

I'm currently facing the following issue with Single Sign-On at my customer's:
The user can enter OTRS directly with no login screen, provided that he is logged into Windows. In other words, SSO works!

But...
When he opens a ticket to view it (AgentTicketZoom action), a Windows authentication popup apears, and the user has to enter his username and password again!

If he doesn't, a server error 401 is showed in place of the content of the article. (See screenshot.)

Here is an example of page code where the issue is:

Code: Select all

<div class="ArticleMailContent">
  <div>
    <iframe id="Iframe347" width="100%" frameborder="0" src="/otrs/index.pl?Action=AgentTicketAttachment;Subaction=HTMLView;ArticleID=347;FileID=2;OTRSAgentInterface=H3x4IF2QJ1pzH7pQubkI5erxeZSPWLsK" onload="window.setTimeout( function (){ if (typeof Core === 'object' && typeof Core.Agent === 'object' && typeof Core.Agent.TicketZoom === 'object') { Core.Agent.TicketZoom.IframeAutoHeight($('#Iframe347')); } }, 500);" security="restricted" sandbox="allow-same-origin allow-popups" style="height: 194px;">
  </div>
</div>

(It seems the issue only occurs with IE8, but my customer is not ready to upgrade their corporate browser so far.)

Is there anything I can do to prevent this issue?

Best regards,
HervE

Found the solution: just added the following code to CSS.

Code: Select all

iframe {
    position: relative;
}
