Do this:
Pass the variable name as a value to the tag, just like the actual value.
<zp:authenticate var="<%=user%>" value="<%userName%>"/>

Subject: Data from a tag library
> Hi,
>
> We're writing a custom tag library for our platform, and for the most
> part it's working quite nicely. When you want to set a java variable in
> a tag you do something like:
>
> <%
> int myVar = 5;
> %>
>
> <zp:foo bar="<%=myVar%>"/>
>
> How do you do the opposite, how do you fetch a var from a tag into your
> java code? I'd like to have a tag that fetches the user name and makes
> it available to the java code. Something like:
>
> <%
> String user = "";
> %>
>
> <zp:authenticate "<%=user%>"=userName/>
>
> <%
> if(userName.equals("joe"))
> ...
> else
> ...
> %>
