Logins Across Linked Servers

Feb 28, 2007

Hi.

I wish to be bale to call a proc on a linked server but i am having difficulty with logins. I have a sql 2000 server linked to a sql 2005 server. To be able to call the proc on 2005 a login for the user must exist on both 2000 and 2005, and the login on 2005 must have access to the db and 'grant execute' on the proc.

Is there a way to allow access to the 2005 db without having to perform maintenance of the logins to ensure they match?

I know i could just have 1 login on 2005 that all users on 2000 are mapped to but this means new users added would have to also be mapped in the future.

Is it possible to call the stored proc on 2000 by impersonating a login that exists on both servers? Something similar to 'EXECUTE AS LOGIN = 'linklogin' in 2005? This would mean all users on 2000 could impersonate this one login and after this ine login is set up no further maintenance is required.

Thanks

As we all know logins and jobs aren't replicated when using AllwaysOn. What i wanna know is if the "tranfer login taks" will be enough to cover the transfer of logins between servers.

Backing Up Logins And Permissions For SQL Servers

May 31, 2006

Hi,I work as an IT Administrator and part of my job role is to useEnterprise Manager and Query Analyzer to backup the logins andpermissions for each database on our SQL Servers. This information isused as a backup in the event of a server failing so we then havesomething to fall back on if we need to add the same logins/permissionsagain.This takes ages to do, as I have to manually enter all the informationinto a spreadsheet.Steps:- In Enterprise Manager I connect to a server then 'Security' tab, then'Logins'. I then enter all items into a spreadsheet.- In Query Analyzer I connect to a server then do 'sp_helpuser' to listall the permissions for each database. I then enter all informationinto a spreadsheet.I was wondering if there is such a program available on the market thatwould do this for me? I know that MS Baseline Security can show flatfile share permissions to a certain degree and was wondering if therewas a similar program out there to help me do my job easier, or ifthere is a simple way of doing this in the future...Any feedback would be greatly appreciated.Regards,Jenny

How Can I Move Logins For A Linked Server?

Jun 25, 2007

I have SQL Server 2005 on a DEV box and I have a linked server on that box.

It has several logins that I would like to move over to our production server when I re-create the linked server.

Now I can export the script to create that linked server, but when I do so it doesn't provide me with the user's login password.

Is there a way to export the password as part of the script so I can move the linked server AND all the users associated to it over to a new server?

Linked Server Issue Using Logins Current Security Context

Nov 9, 2007

From my desktop in Management Studio (MS) I can connect to server A and run a query like,
select top 1 * from serverB.mydatabase.dbo.mytable, and all seems to be working. If I leave and come back after a few minutes it no longer works and I get this error:
Msg 18452, Level 14, State 1, Line 1

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

If I remote connect to server B and run the query it works and when I try it from my desktop MS it starts working again. Any ideas on why this is happening?

Lost SQL Logins, But Still Have DB Logins - Script To Recreate SQL Logins?

Jan 21, 2007

ok, first, I know... I forgot to run a backup of the master database, and I forgot to run a script to caputure logins. Not that that is out of the way... I need to recreate the logins under the Securities tab below the databases. All the company databases have the user names and passwords assigned to them, but they are not able to login, because they are not able to authenticate to the SQL server first.

Is there a script that someone has that will copy the company database security info for the users and recreate them in the SQL security tab?

I know that I can rebuild them manually, but I need to delete them first in the application software, then delete them from the databases, and then recreate them in the application software... and as simple as that sounds... it is a slow moving process.

Any assistance would be greatly appreciated.

Thanks,

John

Linked Servers In DTS...

Jun 25, 2001

Hi,

I'm using SQL Server 7.0 SP1.

I have a DTS package that requires me to link 2 servers
and query both in order to get my set of records that I
want to Transform. My query runs fine in QA. I copy and
paste it into the SQL Query window of the transformation.
I click Preview and all that happens is a quick flicker of
the DTS window. When I go to Transformations, there are
no source columns.

Here is a copy of my code that I'm trying to use:
-------------------------------------------------------
declare@start_dteas datetime,
@end_dteas datetime

SELECT@start_dte = date_data_range_start_dte,
@END_DTE = date_data_range_END_dte
FROMSIDDEV.SID_DEVELOPMENT.DBO.T901_RUN
WHERERUN_ID = (selectmax(run_id)
from
SIDDEV.SID_DEVELOPMENT.DBO.t901_run
whererun_type_cd = 'M')


SELECTRUN_ID
INTO#RUNS
FROMCRMDEV02.MDCORE.DBO.T901_RUN
WHEREDATE_DATA_RANGE_START_DTE >= @START_DTE
ANDDATE_DATA_RANGE_END_DTE <= @END_DTE

SELECTT70.*
FROM
CRMDEV02.MDCORE.DBO.T70_MD_UNIVERSE_RELATIONSHIP_M A
NGT AS T70 JOIN #RUNS
ONT70.RUN_ID = #RUNS.RUN_ID

DROP TABLE #RUNS
------------------------------------------------------
Is there an issue with Linked Servers and DTS?
Any help would be greatly appreciated.

Thanks in advance,

When I create linked server using integrated security and <they will be impersonated> option I get this:
Server: Msg 18456, Level 14, State 1, Line 1 Login failed for user ''
MS Technet says that SQL Server 7 doesn't allow double hops and to use mappings to standard security login to work around. @#%%~~@@#@#&^%@#
Impersonating to version 6.5 works fine.
Is there any way to link servers using ONLY integrated security?
Any help would be much appreciated.

Hi.
I'm working with SQL Server 7.0 and I've been reading about the linked server option. My question is, if it's possible to link a server with a SQLBase database 7.01.

I have download some drivers to my computer, the odbc driver for sqlbase and the sqlbase ole db driver as well, but when I try to add a new linked server in the enterprise, in the provider name option I can not see any provider name addressing to Centura or Sql base driver.

Has anybody an idea how to make this connection then? or the right way for doing it??

Thanks for any help can be offered.
Regards, Elvia.

I have two 7.0 servers and I want to run a distributed query.

I did sp_addlinkedserver to link server B to server A
and I did sp_addlinkedsrvlogin for a specific login.
After adding login when I try to access a table on server B it
says login failed

All the logins are NT authenticated (in both the servers, So
both servers have same logins.)

We are creating a newServer grabbing data from an extrnal data source.

We need to perform regular audits to verify the record counts (for now) are the same.


We have 2 physically separate SQL servers 1 with old 1 with new.

I have created a linked server but when i do a query on the linked server the performace is pathetic (2mins 12 secs) to do a simple count.

Is there a better way, or can improv the perf?

Recently, I had Microsoft review why our SQL Db was unexpectedly terminating. They pointed to our Oracle Linked servers. They recommended that we try to uncheck the enable allow in process option on the ODBC driver. We are currently using the Microsoft OLE Db provider for our Oracle connnections as we were unable to get the Oracle ones to work with a linked server. When we unchecked this allow in process option near the end of the day our website began getting out memory errors from ODBC. It appeared to have been because of this change. Does anyone have any insight as to why changing this option could have caused this?

We have a new 2005 server, and I am trying to link our old 2000 server so I can use the old databases in new server.

This is what I done:
In 2005:
EXEC sp_addlinkedserver oldServer
--completed fine
then:
EXEC sp_addlinkedsrvlogin oldServer, 'false', NULL, 'Administrator', password
--completed fine
But whenI run the query I get the error:

OLE DB provider "SQLNCLI" for linked server "oldServer" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.

Hi,

Disclaimer: I am not a DBA so my attempts may not make sense. :)

I have a win 2003 server running sql server 2005. I am trying to create a 'linked server' with an oracle 8i database at a remote site. I have tried using the 'add linked server' option from sql server enterprise manager and I have also tried to create it using the sp_addlinkedserver command. i tried using a dsn as the datasource and I have also tried using a dsnless connection using a TNS entry as the provider string. The Oracle client is on the box as can be confirmed both by the dropdown in the 'add linked server' dialog in sql server enterprise manager and also by going into the oracle enterprise manager and actually sending oracle data. I don't really have a preference on how to create the 'Linked server', I just need to get it to work.

AAA = server
BBB = DSN
XXX = UID
YYY = pwd

DSNLess Attempt:
EXEC master.dbo.sp_addlinkedserver @server = N'TEST1', @srvproduct=N'OraOLEDB.Oracle', @provider=N'OraOLEDB.Oracle', @provstr=N'SERVER=(DESCRIPTION=(ADDRESS_LIST=(ADDR ESS=(PROTOCOL=TCP)(HOST=AAA)(PORT=1556))) (CONNECT_DATA=(SERVICE_NAME=LPPCPEDB)));uid=XXX;pw d=YYY;'

DSN Attempt:
EXEC master.dbo.sp_addlinkedserver @server = N'TEST2', @srvproduct=N'Oracle', @provider=N'OraOLEDB.Oracle', @datasrc=BBB'

Thanks in Advance

I have a linked server connection on a SQL 2k server connected to a Sybase ASE 12.5 server via Sybase OLE DB connection. To this point everything has been working great for months. Now we're encountering a problem where new tables created on the Sybase db won't show up in the linked server connection. I've checked permissions and the object owners and everything is exactly the same as the pre-existing tables except the table's new.

Anyone have any ideas wht's up???
