problem connecting to Active Directory server in C# .NET -


I am currently writing some software in C #, connecting to an AD server and getting some user details is. When I connect using the code given below, it works against most AD servers which I connect but there are a couple where it is accompanied by an error of "logon failure: unknown user name or incorrect password" Fails The server name / credentials I am using are definitely correct because I have tested them with the LDAP browser and the AD server is using standard security (port 389 etc.). Can anyone offer any advice?

Cheers

  DirectoryInterityD = new directoryInterity ("LDAP: //" + domain, administration_design, admin_password); Try {object x = d.NativeObject; } Hold {throw; }  "

I have programming in the past .net / AD similar problems. I have found, is useful to use an LDAP viewer to see if I can connect to some servers, etc. In this way, I can at least decide that this one. NET error (probably my code), a credential error etc.

I use the free / light version of Softer's LDAP viewer () However, I'm sure there are many more people there to choose from. If you try someone listed here, do not forget to download 'LDAP Browser' and do not 'LDAP Administrator'. The browser is a free one.

Try using the LDAP browser / viewer to connect to the same LDAP path, in which you are having difficulty in code. This will be determined as a minimum step whether it is a .NET / code problem. If you can not connect through the browser, then port options, such as port, domain (FQDN), etc. can be useful to play with.

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
