# LegacyMutualAuthentication

Determines whether mutual authentication is enabled.

Note Mutual authentication is not supported and is not available by default with Windows NT 4.0. This named-value is only useful if the network administrator installs a security provider that supports mutual authentication.

Registry Entry

HKEY_LOCAL_MACHINE\Software\Microsoft\OLE\LegacyMutualAuthentication= value

Remarks

The LegacyMutualAuthentication named-value is a REG_SZ that provides the default setting for use of mutual authentication for all applications that do not call CoInitializeSecurity. Values of “Y” or “y” indicate that mutual authentication is enabled. Any other value or the lack of this named-value implies that mutual authentication is disabled.
