BG_BASIC_CREDENTIALS structure (bits1_5.h)

Identifies the user name and password to authenticate.

Syntax

typedef struct __MIDL_IBackgroundCopyJob2_0001 {
  LPWSTR UserName;
  LPWSTR Password;
} BG_BASIC_CREDENTIALS;

Members

UserName

A null-terminated string that contains the user name to authenticate. The user name is limited to 300 characters, not including the null terminator. The format of the user name depends on the authentication scheme requested. For example, for Basic, NTLM, and Negotiate authentication, the user name is of the form DomainName\UserName. For Passport authentication, the user name is an email address. For more information, see Remarks.

If NULL, default credentials for this session context are used.

Password

A null-terminated string that contains the password in plaintext. The password is limited to 65536 characters, not including the null terminator. The password can be blank. Set it to NULL if UserName is NULL. BITS encrypts the password before persisting the job if a network disconnect occurs or the user logs off.

Live ID encoded passwords are supported through Negotiate 2. For more information about Live IDs, see the Windows Live ID SDK.

Remarks

The following list identifies when the UserName and Password members are required based on the authentication scheme requested:

To protect the user name and password information, call the SecureZeroMemory function, defined in Winbase.h, to clear the UserName and Password buffers after you use the structure.

You can specify the user name like this.

• DomainName\UserName. Use DomainName\UserName if the server is in a domain and the DomainName is the domain to which the server belongs or is a trusted domain.
• ServerName\UserName. Use ServerName\UserName if the account is a local account on the server. The ServerName is the name of the computer that is authenticating the credentials.
• UserName. If you specify only UserName, the user's default domain name is prefixed to the user's name and the rules for the DomainName\UserName form apply. Use this option only if the user is a member of a domain.
• NULL. To use the user's logon credentials for NTLM or Kerberos authentication, set UserName to NULL. This works only if the user is in a trusted domain. Setting UserName to NULL for services running as a system account passes the computer's credentials for authentication. This option works only if the domain enables Kerberos authentication and you select Negotiate as the authentication scheme.
