Asp.net login control redirect to itself -

i have problem login control in asp.net. when entered correct password, login.aspx redirect itself. why? want goto nazarat.aspx after successful login.(account/login.aspx?returnurl=%2fadmin%2fnazarat.aspx)

web.config inside parent folder of nazarat.aspx:

<?xml version="1.0" encoding="utf-8"?> <configuration> <system.web>           <authorization>             <allow roles="admin" />             <deny users="*" />     </authorization> </system.web> </configuration> 

and in login.aspx:

 <asp:login id="loginuser" runat="server" enableviewstate="false"              renderoutertable="false"  >             <layouttemplate>                 .... .... ....              </layouttemplate>         </asp:login>               

is user using login member of role: admin ? per settings:

<allow roles="admin" /> <deny users="*" /> 

any user admin allowed, other users denied access.

may may want use: ? instead of * in:

<allow roles="admin" /> <deny users="?" />
