Missing that drop-down box option on the Web Interface Login Page giving the option to use pass-through or not?
To resolve this issue:
1.In Internet Explorer Options > Security tab, add the Web Interface site to Trusted Sites.
2.Enable compatibility view for the site under Internet Options > Tools > Compatibility View Settings and add the Web Interface site to Compatibility View.
3.Restart Internet Explorer.
If i had a quid for every fix related to IE11 and using that compatibility view settings fix..
Also, handy URL covering this and other fixes relating to citrix and IE11 (the one above was the issue i’d come across after move to v11)
