When I try to login I get this error: DOMParser not defined

Since ASM version 2.6 and above, login happens through an AJAX call.
To parse the answer on IE ActiveX technology is used (Microsoft.XMLDOM, inside IE since version 4).

Two different problems can cause this issue:

1. ActiveX is not installed (unlikely)
2. IE settings prevent ActiveX from working.

To solve the problem verify that ActiveX are allowed at least for ASM site.
