是否可以使用GSSAPI验证Spring LDAP上下文（LdapContextSource）源
Map<String, Object> baseEnvironmentProperties = new HashMap<String,Object>();
LdapContextSource contextSource= new LdapContextSource();
.....
baseEnvironmentProperties.put( Context.SECURITY_AUTHENTICATION, "GSSAPI");
contextSource.setBaseEnvironmentProperties(baseEnvironmentProperties);
Spring Documentation仅讨论DefaultTlsDirContextAuthenticationStrategy和ExternalDirContextAuthenticationStrategy- EXTERNAL SASL TLS
