We have the need to remove the Logout and help links from the top right hand corner of the NPM webpage for everyone except admins as this is generally displayed within an iframe and therefore not required. Below is the code which we modified previously, but in 10.4 this section doesn't appear in the OrionMasterPage.Master:
<%=GetUsername().ToUpper()%> <%-- (<a href="">thwack.solarwinds.com/.../a>)--%>
<%if (AllowAdmin()) { %>
<a href="">thwack.solarwinds.com/.../a>
<a class='indent' href="">thwack.solarwinds.com/.../a>
<%} %>
<a class='indent' href="">thwack.solarwinds.com/.../Help.aspx" target="_blank">Help</a>
Thanks
