[jboss-jira] [JBoss JIRA] (ELY-494) DigestServerFactory should only use AvailableRealmsCallback to get realms, not the legacy property list

DigestServerFactory should only use AvailableRealmsCallback to get realms, not the legacy property list ------------------------------------------------------------------------------------------------------- Key: ELY-494 URL: https://issues.jboss.org/browse/ELY-494 Project: WildFly Elytron Issue Type: Bug Components: SASL Reporter: David Lloyd We use a different delimiter for the {{com.sun.security.sasl.digest.realm}} property than the JDK, which uses commas, spaces, newlines, or tab characters. This makes it impossible to correctly emulate the property to the mechanism while using the callback to acquire the actual list. Since code changes would likely be required to use the new version with only a comma delimiter, it does not serve any compatibility purpose to continue to support this property. Instead we should do three things: * Eliminate property support from our DigestSaslServer * Add a wrapping SaslServerFactory which detects when a mechanism is trying to acquire a realm list by reading the {{com.sun.security.sasl.digest.realm}} property, and uses the AvailableRealmsCallback to populate it (with a flag to support transformation of spaces, tabs, and newlines to NBSP (0xA0), and remove commas) * Add a wrapping SaslServerFactory which allows legacy users to specify a value for {{com.sun.security.sasl.digest.realm}}, and uses it to support AvailableRealmsCallback if that property was set, with programmable delimiters
