All Superinterfaces:

CacheCallback, Declarable
```
@Deprecated
public interface Authenticator
extends CacheCallback
```
Deprecated.
since Geode 1.0, use SecurityManager instead

Specifies the mechanism to verify credentials for a client or peer. Implementations should register name of the static creation function as the security-peer-authenticator system property with all the locators in the distributed system for peer authentication, and as security-client-authenticator for client authentication. For P2P an object is initialized on the group coordinator for each member during the DistributedSystem.connect(Properties) call of a new member. For client-server, an object of this class is created for each connection during the client-server handshake. The static creation function should have the following signature: public static Authenticator [method-name](); i.e. it should be a zero argument function.

Since:

GemFire 5.5

void init(Properties securityProps,
          LogWriter systemLogger,
          LogWriter securityLogger)
   throws AuthenticationFailedException
```
    Deprecated.
    
    Initialize the callback for a client/peer. This is invoked when a new connection from a client/peer is created with the host.
    
    Parameters:
    
    securityProps - the security properties obtained using a call to DistributedSystem.getSecurityProperties()
    
    systemLogger - LogWriter for system logs
    
    securityLogger - LogWriter for security logs
    
    Throws:
    
    AuthenticationFailedException - if some exception occurs during the initialization
  - init
```
default void init(Properties securityProps)
           throws AuthenticationFailedException
```
    Deprecated.
    
    Description copied from interface: Declarable
    
    Initializes a user-defined object using the given properties. Note that any uncaught exception thrown by this method will cause the Cache initialization to fail.
    
    Specified by:
    
    init in interface Declarable
    
    Parameters:
    
    securityProps - Contains the parameters declared in the declarative xml file.
    
    Throws:
    
    AuthenticationFailedException
  - authenticate
```
Principal authenticate(Properties props,
                       DistributedMember member)
                throws AuthenticationFailedException
```
    Deprecated.
    
    Verify the credentials provided in the properties for the client/peer as specified in member ID and returns the principal associated with the client/peer.
    
    Parameters:
    
    props - the credentials of the client/peer as a set of property key/values
    
    member - the DistributedMember object of the connecting client/peer member. NULL when invoked locally on the member initiating the authentication request.
    
    Returns:
    
    the principal for the client/peer when authentication succeeded
    
    Throws:
    
    AuthenticationFailedException - If the authentication of the client/peer fails.
  - authenticate
