Is it possible to use LDAP (not Active Directory) to authenticate users on a MS SQL Server database. We have business users who have SQL user accounts on the database, and want to switch that to an LDAP server (specifically, JumpCloud).
Yes it is possible if you consider this:
Each user has a local machine user account on both the server and the client
The local machine user account names on the server and the client match exactly - case, spaces, characters (handle the accounts with jumpcloud agent).
The passwords for the local machine account on the server and client match exactly - case, spaces, characters (set the passwords from jumpcloud)
Create permissions of local windows users on each sql database you will need to access (On SQL Management studio, expand the database, security, users, right click and add user of type windows user, browse on user name ..., type the username, check name and confirm it)

I have a Microsoft Access Application which generates a connection string like:
Provider=SQLNCLI11;Server=servername;Database=db_name;Trusted_Connection=yes;
This works without any problem.
What I want to do is to connect to a SQL Server instance where the user must insert his Active Directory name and password.
Like this:
Provider=SQLNCLI11;Server=servername;Database=db_name;Uid=username;Pwd=password;
This only works for users which are created on the SQL Server directly.
I tried Uid=DOMAIN\username, but it isn't working.
Is this possible? Or is there another way how I can get through this?
The environment:
The User is using a local PC with a local account and then he's doing a "NetworkConnect" with his AD-User and password.
After that, "RunAs" as his AD-User is working BUT there is another Application that is started from the Access Application and this App must be started with the local User-Account.
SQL-Server and the AD-User are member of the same domain.
Your choices are
Login to SQL Server using your the Windows Domain account that you are currently logged into. You do this automatically by specifying Trusted_Connection=yes;, or
Login to SQL Server using a SQL Login.
Those are the only two choices possible using a SQL provider connection string. Specifically, you cannot use the SQL access provider to do impersonation, that is, to login to SQL Server using a different Windows domain account than the one that you are currently logged into.
Microsoft designed the AD integration with SQL Server to use the account of the client application, not to be able to handle logging in as a part of the connection string. If the user isn't going to be logged into the machine using the account needed for the database access, the next best option may be something like ShellRunAs in order to let the user run your client app as the correct AD account.
Using the example below, which is in my App.Config file, are the uid and password values for the SQL Server, or the SQL Server instance, or for the database that is on the SQL Server?
value="server=localhost;database=myDb;uid=myUser;password=myPass;"
Thanks,

Sql Server separates the concept of a login from a user. A server instance itself has logins. Individual databases hosted on a server instance have users.
When you want to run a query or otherwise interact with a database, you generally first connect to the server. You supply a username (uid) and password that match a server login. This login in turn maps to a user in one (or more!) databases hosted by that server.
You can see the user mappings by opening Sql Server Management Studio and connecting to your server. In the Object Explorer area expand the Security and then Login folders (just under "Databases"). Double-click a login to open it's Properties window, and find the User Mappings section.
The connection string also includes a database. The purpose here is (again) because a login might map to more than one database. Specifying a database as part of the connection provides context, so you don't need a database name with every table reference in your SQL code.
There's also Windows/Active Directory authentication (Integrated Security). This makes things even messier, because you can set up Active Directory groups (in addition to users) as server logins to manage access for a number of people at once. An Active Directory user can belong to more than one of these groups... and thus map to more than one user in a single database. In my experience, when this happens you tend to get the union of the set of permissions from every database user you could claim, but I haven't studied that situation thoroughly.
server=localhost;
This is the location of the server. You can use the IP address or the name of the computer. Localhost means this code is on the same machine as the SQL server
database=myDb;
This is your database. Such as master (which is a system one)
uid=myUser;
This is a login on the SQL server. Make sure that login has permissions to the database you are trying to access (and subsequent tables). See the picture below, that is a login abc_test.
password=myPass;
The password for the above user
It is possible to have those Logins as Windows Authenticated logins but in my experience in code it's usually SQL Server authentication (mixed mode) logins.
As sniperd said You can create a new login with a new username and password by right clicking on Logins. Or you can use an existing Login name and change its password. Hope this gonna work!
I have an domain admin user group and I have added it to SQL Server security. My account is added to the group. But I am not able to log in to SQL Server.
If I add my domain account individually to SQL Server, I can login using my Windows account. Can I login into SQL Server via a user group so I do not have to add the each individual account?
Yes, you can. All that is required is to add the windows ad group to whatever role is appropriate to your configuration.
SQL Server supports three types of logins:
A local Windows user account or trusted domain account. SQL Server
relies on Windows to authenticate the Windows user accounts.
Windows group. Granting access to a Windows group grants access to
all Windows user logins that are members of the group.
SQL Server login. SQL Server stores both the username and a hash of
the password in the master database, by using internal authentication
methods to verify login attempts.

And this article has step by step with screen shots: Step By Step
You can use Windows Authentication Mode, first you need to make sure that the user's identity is verified by Windows then SQL Server validates the account name and password using the Windows principal token in the operating system.

Could somebody explain how you can have different databases/security when connecting in via Windows Authentication from when someone connects via SQL authentication?
I have a customer who had to put a computer onto their network. When they did this, the computer name changed. When connecting into SQL it now has a different server name.
The thing is if I connect using a SQL username and password, I get the databases that were installed before. However If I connect using windows authentication, I do not get the database.
I would like to know what needs to be changed in order for windows authentication to see the same as a user logging in via SQL authentication.
How can I go about changing the permissions of windows authentication?
Within SQL Server, there are Logins (at the server level) and Users (at the database level). Your SQL Server login obviously has permission to the database(s) you want to see. The logins can also be windows users and/or groups. So, if you add a named windows user as a server login, you can extend that login as users in different databases. You can do the same thing with a group. So, you could have a single login to your sql server that represents all authenticated users in your domain, etc...
So, I think you need to get into SSMS (SQL Server Management Studio) and see what logins and users are defined on your SQL Server.
I was troubleshooting a SQL Server 2008 R2 today and the server was generating a ton of connection errors from multiple services. In looking at how the server had been setup the user had a number of services set to run under specific login credentials. The client had setup within the configuration manager the SQL Server default instance to run under the account someusername#somedomain.org with a set password
I saw this used in a number of locations including the SQL Server Analysis Service SQL Server Agent as well as within the IIS app pools and other windows services that communicate with SQL Server. Looking at the SQL console logs the server was churning out failed login errors on the minute.
In the past I have always setup these service accounts using either Network Service (for intranet deployments) or a domain account somedomain\somename that is provisioned to work as a service account. The email address which was being used was not provisioned as a SQL Server login but there was a domain user account domain\someusername added as a SQL Server login on the server. To me these are not the same in SQL Server, domain\someusername != someusername#somedomain.org is that incorrect to assume?
I am in the process of setting everything to a baseline by resetting all the services to use NetworkService so I can at least get everything working properly.
My question is, are there restrictions on using special characters in login's for SQL Server? I had always thought that you did not want( or could not ) use special characters for creating logins such as an email addresses. I know when registering an IIS machine against SQL you can use the machine name as domain\machinename$. It seems to me that an email address is not a valid domain account as it could be an alias etc and that you would want to explicitly use a valid domain user/service account.
Can anyone provide me some reference material on what is allowed? When I search msdn or google I get more results on SQL injections or escaping passwords. I just want to have a more solid understanding of what is allowed as it pertains to a SQL Server login, as well as what a documented best practice is moving forward so when explaining what to do or what not to do I have some legit reference.
The client has the server set to use mixed mode authentication but it looks as if they are trying to set everything up to rely on windows authentication for connectivity to the server.
thanks for any insight,

User Account Objects have two names - a User Principal Name and a SAMID - both of which must be unique in the Forest. These can be seen in the Account tab in Active Directory Users and Computers.
The User Principal Name consist of the logon name followed by a UPN Suffix. For example, andrea#adventure-works.com. UPN Suffixes are properties of the Forest and are unrelated to email domains (though for sanity's sake, they should match email addresses :-).
The SAMID consists of the NetBIOS name of the Active Directory domain followed by the logon name (pre-Windows 2000). For example ADVENTURE-WORKS\andrea.
Most software accepts both types of name but a few accept only one or the other.
