Returns information about Windows users and Windows groups.
Fully qualified Windows account name.
Type of Windows account. Valid values are user or group.
Access privilege for SQL Server. Valid values are admin, user, or null.
mapped login name
For user accounts that have user privilege, mapped login name shows the mapped login name that SQL Server tries to use when logging in with this account by using the mapped rules with the domain name added before it.
Group membership that allowed the account access.
If account_name is specified, xp_logininfo reports the highest privilege level of the specified Windows user or group. If a Windows user has access as both a system administrator and as a domain user, it will be reported as a system administrator. If the user is a member of multiple Windows groups of equal privilege level, only the group that was first granted access to SQL Server is reported.
If account_name is a valid Windows user or group that is not associated with a SQL Server login, an empty result set is returned. If account_name cannot be identified as a valid Windows user or group, an error message is returned.
If account_name and all are specified, all permission paths for the Windows user or group are returned. If account_name is a member of multiple groups, all of which have been granted access to SQL Server, multiple rows are returned. The admin privilege rows are returned before the user privilege rows, and within a privilege level rows are returned in the order in which the corresponding SQL Server logins were created.
If account_name and members are specified, a list of the next-level members of the group is returned. If account_name is a local group, the listing can include local users, domain users, and groups. If account_name is a domain account, the list is made up of domain users. SQL Server must connect to the domain controller to retrieve group membership information. If the server cannot contact the domain controller, no information will be returned.
The following example displays information about the BUILTIN\Administrators Windows group.
EXEC xp_logininfo 'BUILTIN\Administrators'
