A credential is required to connect from a outside resource to SQL Server. I needed to created a proxy to run an Integration Service and I wanted to create a credential for that.
MSDN says that a single credential can be mapped to multiple SQL Server logins and a SQL Server login can be mapped to only one credential. Only users with ALTER ANY CREDENTIAL permission can create or modify a credential.
1.In Object Explorer, expand Security, right-click Credentials, and then click New Credential.
2.In the New Credentials dialog box, in the Credential Name box, type a name for the credential.
3.In the Identity box, type the name of the account used for outgoing connections (when leaving the context of SQL Server). Typically, this will be a Windows user account. But the identity can be an account of another type.
4.In the Password and Confirm password boxes, type the password of the account specified in the Identity box. If Identity is a Windows user account, this is the Windows password. The Password can be blank, if no password is required.
5.Click OK.To create a credential
