Getting the Current User in SharePoint XSLT

SharePoint offers a couple of ways by which we can obtain the current user for use in a XSLT web part like DataFormWebPart or XsltListViewWebPart. All involve first setting parameters through the ParameterBindings property:

   1: <ParameterBindings>
   2:     <ParameterBinding Name="UserID" Location="CAMLVariable" DefaultValue="CurrentUserName"/>
   3:     <ParameterBinding Name="LogonUser_" Location="WPVariable(_LogonUser_)"/>
   4:     <ParameterBinding Name="LogonUser" Location="ServerVariable(LOGON_USER)"/>
   5:     <ParameterBinding Name="AuthUser" Location="ServerVariable(AUTH_USER)"/>
   6:     <ParameterBinding Name="RemoteUser" Location="ServerVariable(REMOTE_USER)"/>
   7: </ParameterBindings>
   8: <Xsl>
   9:     <xsl:stylesheet version="1.0" xmlns:xsl="" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl asp" xmlns:asp="System.Web.UI.WebControls" xmlns:ddwrt2="urn:frontpage:internal" xmlns:ddwrt="">
  10:         <xsl:output method="html" />
  11:         <xsl:param name="UserID"/>
  12:         <xsl:param name="LogonUser_"/>
  13:         <xsl:param name="LogonUser"/>
  14:         <xsl:param name="AuthUser"/>
  15:         <xsl:param name="RemoteUser"/>
  16:         <xsl:template match="/">
  17:             UserID: <xsl:value-of select="$UserID"/><br/>
  18:             ID: <xsl:value-of select="ddwrt:UserLookup($UserID, 'ID')" /><br/>
  19:             EMail: <xsl:value-of select="ddwrt:UserLookup($UserID, 'EMail')" /><br/>
  20:             Login: <xsl:value-of select="ddwrt:UserLookup($UserID, 'Login')" /><br/>
  21:             LogonUser_: <xsl:value-of select="$LogonUser_"/><br/>
  22:             AuthUser: <xsl:value-of select="$AuthUser"/><br/>
  23:             RemoteUser: <xsl:value-of select="$RemoteUser"/><br/>
  24:         </xsl:template>
  25:     </xsl:stylesheet>
  26: </Xsl>

Here we see different kinds of parameters:

  • CAMLVariable: built in variables UserID and Today;
  • WPVariable: returns one of the predefined values for _WPID_ (web part client id), _WPQ_ (web part unique id in page),  _WPR_ (web part resources folder full URL),  _WPSRR_ (web part resources folder relative URL), _LogonUser_ (server variable LOGON_USER),  _WebLocaleId_ (current site locale, as in CultureInfo.LCID);
  • ServerVariable: returns one of the HTTP or IIS server- defined variables.

This will return something like this:

UserID: Ricardo Peres

ID: 10


Login: i:0#.w|DOMAIN\ricardoperes

LogonUser_: 0#.w|DOMAIN\ricardoperes

AuthUser: 0#.w|DOMAIN\ricardoperes

RemoteUser: 0#.w|DOMAIN\ricardoperes

The ddwrt:UserLookup extension function returns a value depending on the second parameter; valid values are Id, Email and Login, and you can easily guess what they are for.

You can find a reference for LOGON_USER, AUTH_USER, REMOTE_USER and UNMAPPED_REMOTE_USER here. In my development server, I get the same value for all variables.

By the way, I posted a more advanced solution, which allows access to any profile properties. You can read it here.
