DB Engine :: Authentication After Password Change On MSAs
Jul 30, 2015
We are experiencing authentication/ Kerberos issues after a password for the MSA's has changed. We use MSA for our SQL 2012 and windows 2012 combination Servers. This errors creates issues while backing up and Service Broker connectivity.We had to restart sql services to fix it, but this not seem to be a resolution for me because the next time the password changes on these MSA's we may have to restart sql services.There seems to be a known issue for windows 2008 R2 servers and fix is available and we incorporated it. But the issue we are facing is on windows 2012 Server.

This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:
2015-04-27 10:10:32.98 Backup BACKUP DATABASE successfully processed 0 pages in 0.451 seconds (0.000 MB/sec).2015-04-28 00:00:41.90 spid18s This instance of SQL Server has been using a process ID of 2096 since 4/21/2015 9:08:05 AM (local) 4/21/2015 1:08:05 PM (UTC).

This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).

We need to use SQL Server Authentication for some reason and would like to enforce Password Policy with 90-day expiration period. I found "Change password" dialogue appears when I first logged in with the new user, but don't know
(1)what happens when the user failed to change the password before it's expired or
(2)how a user can change his password in advance of the expiration date with no particular server-level permission.

We ran into weird/interesting issue with below details.
Version: Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64) Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200):
We are using SQLCMD to run DDL script on our product database in below order. That script has below content.
step # 1 - database collation change (case -sensitive) statement as very first statement of the script
step # 2 - Actual DDL SQL statements
step # 3 - database collation change back to original (case insensitive)
When we execute all above 3 steps in single script using SQLCMD on our test_server#1 , it is successful but when same is being implemented on test_ server#2 , it is failing.We ensured that there is no other user accessing the db and setting on both the server are all default/basic. Separating out all 3 steps in 3 different script working fine. This is only problem when we combine them into single script and fire it using SQLCMD. If it is something related to session/transaction then we should hit same issue on our test_server#1 server as well but that is not the case.test_server#1 and test_server#2 has exact same database/data, just two different physical machine & SQL Server instance.

Hi,
I am trying to create a new login with a password. I go to Microsoft sql server management. Right-click on security and create a new login with a custom login and password.I use sql authentication. Now after creation if I check the property of the login, the password is the of same length as 'sa'.
The problem is I dont know 'sa' password even. (I use windows authentication to connect to the server.) I need a proper uid and pwd for my .Net application access.
Please help
Thanks

I use DNS alias to access my database server:
server name is -> SRV100
DNS Alias is -> SQLPROD
I've noticed that, using Windows authentication, if I connect to the server using its server name, the DB Engine uses Kerberos authentication scheme (as it is supposed to do) but if I use Kerberos authentication, I see that the DB Engine uses the NTLM authentication
scheme
select client_net_address,auth_scheme from sys.dm_exec_connections
I need to use DNS alias to connect to my server and I want to use Kerberso auth scheme.

I'm trying to connect to a SQL Server 2005 database engine on a local network server. When I am presented with the Connect to Server dialog box, if I select Windows Authentication from the Authentication drop-down, the User name & Password area is grayed out and unusable. The domain user account I'm authenticated with is visible, but grayed out, and the password field is blank and unusable. I'd like to be able to connect as described in help:
User name
Enter the user name to connect with. This option is only available if you have selected to connect using Windows Authentication.
I can connect with either SQL Server or Windows authentication... but with Windows Authentication I'd love to be able to type a specific user name to select with :-)

I have a web app, designed using VWD Express and using SQL 2005 Express. It has a mdf database called "client". It was created using security of windows authentication. I have already changed my instance of sql server express to accept mixed windows and sql authentication.
How do I change my "client" database's permissions to the sql authentication? I need to add a user name and password as a requirement for my web host to be able to attach the mdf to their instance of sql 2005. It has to be the same user and password as I use with my web host's sql server 2005.
Thank you in advance.

Is there any description on what the Remember Password check box on this dialog box does? As far as I can tell, it doesn't do anything. Every time I open an item from a project, or create a new Query, I get asked for the password, no matter how many times I have given it for the Server before.
It looks so useful, but is frustrating not knowing how to use it.
Thanks,
-Rob

Just like with Access DB, can we set password for database in SQL Server 2005 Express ?
Reason to do so is, user with Login having sysadmin previliage can acess all databases in SQL server.
so just want to restrict database access to only those users who knows the password.
Is there any possible solution ? Pls comment.
Thanks.

Hello-
I recently inherited a SQL 2005 Standard database that I am being asked to change the Server authentication mode for. SQL system is managing a local database for Microsoft Systems Management Server 2003. Currently the system is running in SQL Server & Windows authentication mode. I am going to change it to Windows Authentication mode. Can someone point me to a checklist I could refer to before I make the change to be sure I don't take down my database?
Thanks in advance.

Hello, I have several SQL 2000 logins on our servers. I removed the builtin/ groups and only have SQL authentication users, although the server is operating in "Mixed Mode". How can I secure this? I don't understand how we can just connect to any DB without ever being asked to log in. Let me know if you can help. Thanks.

I have one server out of 6 that lets me logon as SA with the default password
of null.
If I run this command to change the password I get password changed, but it
did not change it, I still can logon as SA with the NULL password.
exec sp_password NULL, abc123, 'sa'

I've searched this forum and was surprised to not find this asked before - Is there any way to change SA's password (we have managed to lose it somehow)? And we do have physical access to our SQL Server of course...if that helps.

I have my SQL 7.0 server set for Mixed security. I see now (finally)the advantages of having windows authentication security for windowsgroups.I do most of my developing in Access Projects which require a login ofsome type. I have been using my SQL login to develop with SQL andthen when I give it to the user, I set the project to use Windowsauthentication. I want to be able to have Windows authentication onmy domain account but the user name for my windows account is the sameas my SQL account and it won't let me change the existing account.Now what happens is after I develop the product I have to have theuser login and go in and change to windows authentication. It won'tlet me do it with my sql account.I fear that if I delete my sql account and create a windowsauthentication account all the views, sps, etc. that I have createdwill still have the reference to the sql login and therefore not work.Do I need to have a generic sql account for developing? One thought Ihad was to create a new domain account so I can create that windowslogin and at least get my most recent projects working like I want to?Hope this makes sense to someone.Thanks in advance for your time.Sherry

I am trying to change password, using the code below.. The code below is in a stored proc and I am passing these parameters from a web application.....
sp_password [ [ @old = ] 'old_password' , ] { [ @new =] 'new_password' } [ , [ @loginame = ] 'login' ]
sp_password 'cust1','cust2','cust1'
Server: Msg 15210, Level 16, State 1, Procedure sp_password, Line 20Only members of the sysadmin role can use the loginame option. The password was not changed.
I made my user part of the db_securityadmin role, but that does not help...
How can I give the above mentioned permissions, so that when user cust1 logs on then he can chnage his own password from the web application as long he has given his old password correctly?
