Method Detail

doAuthenticate

protected boolean doAuthenticate(Request request,
                                 javax.servlet.http.HttpServletResponse response)
                          throws IOException

Specified by:

doAuthenticate in class AuthenticatorBase

Throws:

IOException

getAuthMethod

protected String getAuthMethod()

Specified by:

getAuthMethod in class AuthenticatorBase

setLoginEntryName

public void setLoginEntryName(String loginEntryName)

Sets the login entry name which establishes the security context.

Parameters:

loginEntryName - the login entry name

getLoginEntryName

public String getLoginEntryName()

Returns the configured login entry name.

Returns:

the login entry name

isOmitErrorMessages

public boolean isOmitErrorMessages()

Indicates whether error messages are responded to the client.

Returns:

indicator for error message omission

setOmitErrorMessages

public void setOmitErrorMessages(boolean omitErrorMessages)

Sets whether error messages are responded to the client.

Parameters:

omitErrorMessages - indicator to error omit messages

isErrorMessagesAsHeaders

public boolean isErrorMessagesAsHeaders()

Indicates whether error messages will be responded as headers.

Returns:

indicates whether error messages will be responded as headers

setErrorMessagesAsHeaders

public void setErrorMessagesAsHeaders(boolean errorMessagesAsHeaders)

Sets whether error messages will be returned as headers.

It is not always desired or necessary to produce an error page, e.g., non-human clients do not analyze it anyway but have to consume the response (wasted time and resources). When a client issues a request, the server will write the error messages to either one header: Auth-Error or Server-Error.

Technically speaking, HttpServletResponse.setStatus(int) will be called instead of HttpServletResponse.sendError(int, String).

Parameters:

errorMessagesAsHeaders - indicates whether error messages will be responded as headers

isStoreDelegatedCredential

public boolean isStoreDelegatedCredential()

Indicates whether client's (initiator's) delegated credential is stored in the user principal.

Returns:

indicates whether client's (initiator's) delegated credential is stored in the user principal.

setStoreDelegatedCredential

public void setStoreDelegatedCredential(boolean storeDelegatedCredential)

Sets whether client's (initiator's) delegated credential is stored in the user principal.

Parameters:

storeDelegatedCredential - the store delegated credential indication
