Trying to use use SharpSVN in an ASP.NET app. So far, it's been nothing but trouble. First, I kept getting permission errors on "lock" files (that don't exist), even though NETWORK SERVICE has full permissions on the directories. Finally in frustration I just granted Everyone full control. Now I get a new error:
OPTIONS of 'https://server/svn/repo': authorization failed: Could not authenticate to server: rejected Basic challenge (https://server)
This happens whether I have the DefaultCredentials set below or not:
using (SvnClient client = new SvnClient())
{
//client.Authentication.DefaultCredentials = new System.Net.NetworkCredential("user", "password");
client.LoadConfiguration(#"C:\users\myuser\AppData\Roaming\Subversion");
SvnUpdateResult result;
client.Update(workingdir, out result);
}
Any clues? I wish there was SOME documentation with this library, as it seems so useful.
The user you need to grant permission is most likely the ASPNET user, as that's the user the ASP.NET code runs as by default.
ASPNET user is a local account, preferably youd'd want to run this code in an Impersonate block, using a network account set up for this specific reason

I've tried everything possible, to setup nJupiter.DataAccess.Ldap as the membership provider on our intranet based web application built using asp.net 3.5.
Challenges I am facing:
Not able to authenticate the user using the default login webpart (says Your login attempt was not successful. Please try again)
I tried this code and I receive a COMException : "There is no such object on the server."
var ldapMembershipUser = System.Web.Security.Membership.GetUser("username") as LdapMembershipUser;
if (ldapMembershipUser != null)
{
var givenName = ldapMembershipUser.Attributes["givenName"];
}
I have placed my web.config and the nJupiter.DataAccess.Ldap.config here:
web.config : http://pastebin.com/9XdDnhUH
nJupiter.DataAccess.Ldap.config : http://pastebin.com/WsSEhi98
I have tried all possible permutations and combinations for different values in the XML and i am not able to take it forward. Please guide. I just am not able to connec to the LDAP and authenticate the user or even search for users.
Just looking at your config is unlikely to be enough since I don't know your Domino server's confguration, so my answer isn't an attempt to fix your problem. It's an attempt to teach you how I would approach it if it were my problem. Here's what I do to troubleshoot connections and queries from code to Domino LDAP:
Configure the Domino LDAP server for logging the highest level of debug information with the notes.ini setting LDAPDEBUG=7. See this IBM technote for more info.
Use an LDAP client and figure out how to successfully connect to the Domino LDAP server. I like the free Softerra client for this. Check the logs and save off the info from your successful connection.
Now run your code and compare what you see in the logs against the successful connection.
If the code is making it past authentication but failing on the query, then find the actual query in the log, go back to your LDAP client, figure out what the query should have been, and adjust your code's configuration appropriately.
I am working on a small project, in asp.net mvc3, that would copy the deployment files from a local drive to a share drive on a window server 2008 R2 server. I am connected using WMI, and the connection is successful. However, I tried to create a folder, and I receive the message "Logon failure: unknown user name or bad password." Here is a sample code:
bool isConnected = false;
options.Username = user.Name.Trim();
options.Password = user.password.Trim();
mScope = new ManagementScope("\\\\xxx.xxx.xxx.xxx\\root\\cimv2", options);
mScope.Connect();
if (mScope.IsConnected == true)
{
//I've gotten to this point. Then, the code below throw the exception
Directory.CreateDirectory(#"\\\\xxx.xxx.xxx.xxx\Tester\shareFile.txt");
isConnected = true;
}
I'd like to know what am I doing? Is that the right way of doing it?
it is the correct way however it will be the current user you are trying to access that gets passed to the remote computer to create the directory. The management scope at this point has nothing to do with Directory.CreateDirectory. These are 2 different "worlds". you do give the creds to ManagementScope but this has no affect on Directory.CreateDirectory. you could use impersonation to do what you are wanting to:
How do you do Impersonation in .NET?
it is unclear though if you are doing this in ASP.NET/MVC or a different platform. your tags indicate ASP.NET MVC but not your main question.
remember, if you are using ASP.NET/MVC, the credentials of the app pool are being used to perform such actions.
I have only recently been looking into ACS, AAL, WAAD and I would like to avoid redirecting users to the login page of their IDP. I want to keep my users within my site and present them with a dropdown to choose who they wish to authenticate with and an area to request a username and password, then acquire token via code. Is this possible?
I have been reviewing some sample applications and produce a quick mock-up, but cant seem to get things working e.g.
_authContext = new AuthenticationContext("https://littledeadbunny.accesscontrol.windows.net");
string enteredEmailDomain = UserNameTextbox.Text.Substring(UserNameTextbox.Text.IndexOf('#') + 1);
IList<IdentityProviderDescriptor> idpdList = _authContext.GetProviders("http://littledeadbunny.com/NonInteractive");
foreach (IdentityProviderDescriptor idpd in idpdList)
{
if (String.Compare(ServiceRealmDropDownList.SelectedValue, idpd.Name, StringComparison.OrdinalIgnoreCase) == 0)
{
Credential credential;
credential = new UsernamePasswordCredential(enteredEmailDomain, UserNameTextbox.Text, PasswordTextbox.Text);
_assertionCredential = _authContext.AcquireToken("http://littledeadbunny.com/NonInteractive", idpd, credential);
return;
}
}
Using the code above, when I try to use the Windows Azure Active Directory User (admin), i get the error "Data at the root level is invalid. Line 1, position 1." where I attempt to acquiretoken.
When I use Google, I get an error "0x8010000C: No identity provider matches the requested protocol".
If there is a working sample? if I am doing something obviously wrong, I would appreciate the correction.
This is not supported for passive identity providers. IdPs like Google, Facebook, etc. don't want other people collecting credentials for them, as this leads to security issues and possible phishing attacks. They also don't support it because they need to be able to show a permission dialog (that screen that asks the user if they want to release data to you) which they can't do without the browser redirecting to them. Furthermore, Google in particular supports two-factor auth, which you couldn't replicate, and generally collecting credentials opens up whole cans of worms around other UI problems such as incorrect or forgotten passwords.
This is also generally a bad user experience, because your users are fairly likely to already be logged in to Google and have cookies there. If so, and if they've already consented to your app, they would just be silently redirected back to you. In your scenario, even if the user is already logged in they'd still have to provide a username/password.
The correct way to do these sorts of logins is to render a browser control in your app that allows the user to log in at their IdP, which is what AAL helps with.
I had the same error, executing a powerscript solved that error
PS C:\windows\system32> $replyUrl = New-MsolServicePrincipalAddresses
-Address https://mydomain.accesscontrol.windows.net/
PS C:\windows\system32> New-MsolServicePrincipal -ServicePrincipalNames
#("https://mydomain.accesscontrol.windows.net/") -DisplayName
"MyDomain Namespace" -Addresses $replyUrl
But i'm stuck anyway with a 403 permission error
If you get any further i would like to know how :)
I'm planning to use this piece of code in my Asp.net app
string strUserInputtedHashedPassword = FormsAuthentication.HashPasswordForStoringInConfigFile(tbPassword.Text, "sha1");
if(strUserInputtedHashedPassword == GetUsersHashedPasswordUsingUserName(tbUserName.Text))
{
// sign-in successful
}
else
{
// sign-in failed
}
Is the Hashing machine dependent... In the sense, If I create some users in my development machine in my development DB... Once I post both DB and Application to production environment with the user table, will the password for the users be same...
Hope I made my question clearly... Otherwise, please let me know..
Thanks
The hash is encoded and decoded using the machineKey in the machine.config, if you want the key to work against all tiers, make sure the keys in the machine.config files match.
This is basically the same problem you encounter with a web farm serving requests and validating each other's cookies...same solution.
I have a Windows 2003 server running IIS 6 and have some scripts that do automated setup and creation of websites. They are not working on a new server I cam commissioning (they already work happily on 3 other W2K3 servers). The problem appear to boil down to WMI security on the IIS provider. The ASP code below represents the problem (although it is not the original code that causes the problem - this is a simplified demonstration of the problem).
Set wmiProvider = GetObject("winmgmts:\\.\root\MicrosoftIISv2")
If wmiProvider is Nothing Then
Response.Write "Failed to get WMI provider MicrosoftIISv2<br>"
End If
Response.Write "Querying for IISWebService...<br>"
Set colItems = wmiProvider.ExecQuery("Select * From IISWebServer",,0)
Response.Write "Error: " & Hex(Err.Number) & " (" & Err.Description & ")<br>"
If I run this in my browser, I get an access denied error reported after the ExecQuery call. I have set WMI access for the IUSR_ user from the Root branch all the way down. In fact, I can query for IP address information using the CIMV2 provider quite happily. If I put the IUSR user in the machine admins group it all works, but I don't really want to do that.
This must be a DCOM/WMI security problem, but I can't work out what else there is. Can anyone shed any light?
After reading G. Stoynev's comment asking if any events were logged in the Windows Logs, I checked the event logs on the server to which I'm attempting to access IIS remotely via WMI, and lo and behold I found an event with the following text:
Access to the root\WebAdministration namespace was denied because the namespace is marked with RequiresEncryption but the script or application attempted to connect to this namespace with an authentication level below Pkt_Privacy. Change the authentication level to Pkt_Privacy and run the script or application again.
See the code in this answer to the related SO question c# - "Access is denied" Exception with WMI.
Here's some example C# code that I added that seemed to resolve this issue for me:
ConnectionOptions options = new ConnectionOptions();
options.Authentication = AuthenticationLevel.PacketPrivacy;
ManagementScope managementScope = new ManagementScope(#"\\remote-server\root\WebAdministration", options);
// ...
If this is something that you intend to run as a tool for yourself or your admin (as opposed to the unwashed anonymous masses), here is a way I have used in the past (YMMV):
Set up a new directory in your website (e.g. /SiteCreate) and place your WMI scripts there
Configure a Windows user that has appropriate rights (probably admin in this case but you should use whatever is pertinent to your app)
Turn off the anonymous access to the directory you created in step 1 and then set the security to allow access only to the user you created in step 2 (turn on the authentication for that directory)
Now, when you navigate to that directory in your browser, you should get a login prompt. When you enter the username/password you created in step 2 your script will have the appropriate rights to perform your WMI requests.
Not a DCOM issue, more so a WMI security and encryption issue. Try changing the GetObject moniker to include impersonation and pktPrivacy, eg:
Set wmiProvider = GetObject("winmgmts:{impersonationLevel=impersonate;authenticationLevel=pktPrivacy}!\root\MicrosoftIISv2")
