Security :: Suddenly IE Users Cannot Login To Website

Jan 23, 2011

asp.net 3.5 IIS7 Hosted on Windows Server 2008 (virtual machine)

I have a website which have been running for about a year without any problems. Users have been able to login etc, but now I get reports about users not able to login while using Internet Explorer. Users using other internet browsers like FireFox, Chrome etc have no trouble logging in.

The website are using the standard Forms authentication.

Also lately another website has been setup in IIS7, but these sites are using application pool. I've stopped this webapplication in IIS, but that doesn't have any effect on my problem

I see that Windows Update have failed to install a lot of patches lately, not sure if that is related to this problem. But some of the windows patches are security patches.

Users Cannot Login To WebSite After Files Moved

Jun 25, 2010

VWD 2010 Express. Windows 2003 Server. I decided to move my web site from the Inetpub folder on my C: drive to an Inetpub folder on my D: drive to free up space on C:. I moved three web sites. Two of the sites worked fine after the move (I went into IIS 6.0 and changed the home directory of all the sites). One site, which requires authentication using the Windows Active Directory (AD), did not work properly. I could access the site and login with any administrator login. But all other users, although they enter the correct credential, continue to be reprompted for their username and password. The site uses "basic authetication" to check users credentials against the AD. Can anyone think of a reason I would have this peculiar behaviour just because I move a web site's files from C:inetpub to D:Inetpub?

Security :: Allow Clients To Login To Website And Connect To Specific Server Based On Login

Jul 5, 2010

We have created a windows application which is distributed amongst our clients. The application uses SQL Server 2008 as the back end and each client uses their own database on their own server. The databases are all exactly the same but each clients data is specific only to them.

We would like to offer our clients the ability to log-in to our website which would then login to their own database so that when they are out in the field they can perform similar tasks to what they can do with the windows app.Each of the clients databases has a user table containing their login details, permissions etc.

Our server is running on IIS and has SQL Server 2008 installed but it only contains our data and nothing of the clients.How should we go about this?

What I mean is do we need to make each client have an additional login to our main server which would then hold each clients individual connection strings etc which would then be used to connect to there specific database and then they would need to login again?? Seems like a nightmare for the user.

Should my login page not be a content page?

Security :: CAC Login To Web App Without Users Entering ID/PW?

Jan 10, 2010

how to write/use/implement a script that will allow users to enter a web application by clicking a button rather than entering their ID/PW? Seems like a lot of terminology around, SSO, Blind logon, yet all seem to be doable with an ASP script -

Web App contains detailed security for users, not all users are on Win AD, so that is not an option., I'm told (?) Do I need to use a spreadsheet to validate users access to the application, ?

Script that would pass "cookie" info and allow users to enter app without ID/PW. We have a custom logon.asp page the is using forms.

Security :: Asp Login With Multiple Users?

Jun 25, 2010

I have an asp login control that uses the standard aspnet database structure.I am using my own user identification system to identify a user based on login values that are not in the aspnet database and setting the user's aspnet database login to a universal login user and password.this works fine and I am able to test this by having one machine log in as "User 1" and another login as "User 2" but I am wondering if there is a limit to the number of user's that can be assigned to one username and password in the aspnet database for website access?Will the system reach the max number of user's in the aspnet database?

I've got a website project and I use my own login security and save the user and other info in session variables. Is there any way to know when they are online and offline by their user name I have in a session variable? Or do I need to use another method such as the asp.net user security?

Security :: Auto Login To Website?

Jul 5, 2010

I wrote a code using VB.Net that passes the login information to website in order to do the login process automatically.

The code worked with some site and didn't with others specially this site [URL]

I analyzed the login <Form> of the site in the login page [URL] and it looks like this:

<form name="frm_Login" method="post" action="login.cfm">
<input type="hidden" name="Go" value="Reg">
<b style="font-family:Verdana;font-weight:bold;color:#3975B0">Digital Library+</b>
<label id="lbluname" for="username" style="width:150px">Username</label>

[Code].....

So, when i don't use Response.Redirect, the login succeeded, but all the links in the Response data refers to my development server, for example if i click on "support" link, it'll redirect the page to ("http://localhost:3506/support.cfm")!! which will rais of cource "The resource cannot be found" error

And when i use Response.Redirect, i'll loose the session, mean it'll not keep my login for the site.
