Question

Any idea why LoginControl requires users authenticate twice with FireFox but works correctly (once) with IE? I am using a custom MembershipProvider and RoleProvider, if that matters.

Authentication portion of my web.config;

<authentication mode='Forms'>       <forms           timeout='50000000'           protection='All'           requireSSL='false'           slidingExpiration='true'           cookieless='AutoDetect'           domain=''           enableCrossAppRedirects='true'>         <credentials passwordFormat='SHA1' />      </forms>         </authentication> 

Membership section;

    <membership defaultProvider='CustomMembershipProvider'>         <providers>             <add      name='CustomMembershipProvider'      type='CustomCrateMembershipProvider'      connectionString=''      enablePasswordRetrieval='false'      enablePasswordReset='true'      requiresQuestionAndAnswer='true'      applicationName='/'      requiresUniqueEmail='true'      passwordFormat='Hashed'      maxInvalidPasswordAttempts='5'      minRequiredPasswordLength='5'      minRequiredNonalphanumericCharacters='1'      passwordAttemptWindow='10'      passwordStrengthRegularExpression=''/>         </providers>     </membership>     <roleManager defaultProvider='CustomRoleProvider' enabled='true'>         <providers>             <add name='CustomRoleProvider' type='CustomRoleProvider'/>         </providers>     </roleManager> 

Only code behind related to login;

protected void OnLoggedIn(object sender, EventArgs e) { }  protected void OnLoggingOut(object sender, EventArgs e) { }

Hmmm… It does seem odd that it would work in IE but not in Firefox.

Try adding this to your forms-settings:

loginUrl='~/Login.aspx' defaultUrl='default.aspx'
