c# connecting to Active Directory over ssl give ldap server unavailable
LdapConnection ldapConnection = new LdapConnection(server + ":" + port); ldapConnection.AuthType = AuthType.Basic; ldapConnection.Credential = new System.Net.NetworkCredential(username, password); ldapConnection.SessionOptions.ProtocolVersion = 3; if (sslEnabled) { ldapConnection.SessionOptions.SecureSocketLayer = sslEnabled; } This is what I did and I am able to connect to AD over SSL. You said you have Java program connecting to the same server over SSL. Are you running the Java program from the same machine as your c#? if not and in case of a self signed certificate in AD, install that certificate in your client machine and try.

Comparing a hashed password with Active Directory
I don't know a way to do it with LDAP, but it can be done with Kerberos. A good starting point is Kerberos Authentication Technical Reference on technet. You may also want to check Logon and Authentication Technologies, which is the parent article and list a bunch of ways to authenticate against AD, with which I am not familiar.

Poll for only password change in Active Directory
As far as I know, by default the password (stored in an encrypted way) cant't be read in Active-Directory. You can change the policy to store it in a reversible way, but it's really not a good thing. The only way I know, is to install a componant on each client machine. The component catch the password change and you can do what you want. From NT to XP this component was called GINA (DLL). Begining Vista this companent should be written using Credential Provider API.

Regular expression for Active Directory Password
Regular expressions are a great tool, but don't solve everything. E.g., a regular expression can't count in the sense that you require. Yes, a regular expression can count e.g. consecutive letters, but it can't check that you e.g. have two of these and three of the others, spread over the complete input string. This also goes for your specific question. Specifically, checking these two different conditions in the same regular expression may become very difficult. In this case, I would advise not to use regular expressions and just write a small algorithm that performs all checks. Another advantage you get with this approach, is that mere mortals will be able to understand you algorithm when they revisit it later on. Always an added benefit.

Tomcat 6 - authentication through active directory with encrypted password
I think your only alternative is to subclass JNDIRealm and make a new attribute that will have some sort of encrypted connection password. The password can't be hashed (with, e.g. MD5 as you specify) because hashes are one-way--there's no undoing a hash--and Tomcat needs the password in its original unhashed form to authenticate against the AD installation. If you use a reversible encryption in your JNDIRealm subclass, then when Tomcat needs the password you can decrypt the password and pass it along.

The remote server returned an error: (550) File unavailable(Error occured on making ftp directory)
Your code look fine.......you are saying that you have assigned permission too. The only problem is that you may be passing a wrong "Source"which is causing problem..Check your source string it may have an error...... path should be like WebRequest request = WebRequest.Create("ftp://host.com/directory123"); it mean directory will be created with name "directory12" if your are specifying path like this WebRequest request = WebRequest.Create("ftp://host.com/directory123/directory1234"); this mean "ftp://host.com/directory123/" should already exist and new directory will be created with name "directory1234" hope it will help

I did some research and found other applications having similar issues. 1. Make sure you have imported your certificates into the keystore according to the Connect to LDAP or Other Services Via SSL instructions. 2. Make sure any certificates have been imported into the correct keystore; you may have multiple JDKs.

ASP.NET MembershipProvider - SQL Server vs. Active Directory
Your question is unanswerable, as "performance" depends greatly upon many factors.. for instance, network speed, network latency, network saturation, the power of your AD server vs your SQL Server, the disk subsystems in use in either, etc... There is no way to say one way or the other without thoroughly evaluating each environment, and even at that point, you should just benchmark each and determine what works best for you. In most cases, though.. the decision between sql vs ad has nothing to do with performance, and has to do with the features offered by each. I would strongly doubt you have 100,000 users in your active directory, as that would cost a millions of dollars in licensing costs.

How to return user details from the Active Directory using PrincipalContext
I don't understand why you are mixing the new PrincipalContext with the old DirectoryEntry stuff. Doesn't make any sense..... Also - you're searching for all users, but in the end, you're returning only a single DirectoryEntry - why?!? If you're using the new PrincipalContext - then use the UserPrincipal - it contains nice and easy to use properties about the user - much easier to use and work with than the old DirectoryEntry stuf.... public List<UserPrincipal> GetAllUsersDetails() { using (var context = new PrincipalContext(ContextType.Domain, "WIN-SPDEV.com")) using (var searcher = new PrincipalSearcher(new UserPrincipal(context))) { var searchResults = searcher.FindAll(); List<UserPrincipal> results = new List<UserPrincipal>();

To retrieve logged in user's Active directory data from Websphere
Logged on user is represented as a set of principals within JAAS subject. Information like user name or email is not present there and is not supposed to. You have no other option other than query LDAP (Active Directory in your case). The statement like "i have already connected to active directory" does not make much sense. Yes, the user is authenticated by WAS through AD, but this does not mean that any sort of persistent connection exists.

Then you can use that array to simply check if the computer is in the given OU ($CheckOU) or not by using the -match operator. Note: You

Determine User Active Directory Groups from Local Machine off Network
From the top: My current project requires that I validate a user against Active Directory groups. The catch is, the computer may not always be connected to the domain but users may still need to run the tool. At this point, you must therefore accept that any enforced security is able to be bypassed by an attacker since it is entirely enforced on the client. Not exactly part of the solution, but keep it in mind. I understand that I can't query Active Directory while I'm not connected, instead I'm trying to query the Machine SAM (MSAM). The Security Accounts Manager only stores the local accounts (MACHINENAMEAdministrator and others). It will not have domain user credentials. You are thinking of the LSA cache, which remembers the last N domain logins's credentials (where

Anyway). My 2c.

Updating encrypted password-hash stored in XML file to sync with domain password changes
I wrote a bash script that works okay for the purpose. It requires a small addition in ~/.m2/settings.xml for support (see below). The script takes one optional argument: a regex-string used to match optional tag(s) associated with one or more password-hashes in the xml file. I'm using this to indicate Domain-Name, but it could be anything (or nothing, since it is optional). The script prompts for the new password to be hashed, it constrains the newly-generated hash to be pure alpha-numeric (to avoid potential issues with unintended shell-escapes elsewhere), it makes a backup copy of the settings.xml file, and then it updates the selected hashes in settings.xml. Here is the script: #!/bin/bash # Update instances of password-hashes in ~/.m2/settings.xml for a given password [and doma
