* We must add { @link BootDefaultingAuthenticationConfigurerAdapter } in the
* init phase of the last { @link GlobalAuthenticationConfigurerAdapter } . The
* reason is that the typical flow is something like :
*
* < ul >
* < li > A
* { @link GlobalAuthenticationConfigurerAdapter # init ( AuthenticationManagerBuilder ) }
* exists that adds a { @link SecurityConfigurer } to the
* { @link AuthenticationManagerBuilder } < / li >
* < li >
* { @link AuthenticationManagerConfiguration # init ( AuthenticationManagerBuilder ) }
* adds BootDefaultingAuthenticationConfigurerAdapter so it is after the
* { @link SecurityConfigurer } in the first step < / li >
* < li > We then can default an { @link AuthenticationProvider } if necessary .
* Note we can only invoke the
* { @link AuthenticationManagerBuilder # authenticationProvider ( AuthenticationProvider ) }
* method since all other methods add a { @link SecurityConfigurer } which is
* not allowed in the configure stage . It is not allowed because we
* guarantee all init methods are invoked before configure , which cannot be
* guaranteed at this point . < / li >
