Larry - change toprigth username

[danethz]

Hi!
Can I somehow change the top-right username in Larry theme?
I can see it in "larry/includes/header.html":

Code Select Expand

<roundcube:if condition="!env:extwin &amp;&amp; !env:framed" />
<span class="username"><roundcube:object name="username" /></span>

I have several servers, which authenticated via Windows AD.
In case of some user it will be:
username - user1@domain1.local
e-mail - user1@domain2.local
But in Larry theme in topright it shows username, not the e-mail address.
Can I change it?
Thanks
