I have written test for JBPAPP-7794 and I found some errors. I get WARN log ("Invalid or misspelled option:") if I use <module-option name="useObjectCredential"> in LdapLoginModule. Next WARN log I get in LdapExtLoginModule if I use <module-option name="roleAttributeIsDN"> or <module-option name="java.naming.referral">. However, that property should be correct login module option (or there is a mistake in documentation http://documentation-devel.engineering.redhat.com/docs/en-US/JBoss_Enterprise_Application_Platform/5/html/Security_Guide/ch12.html).

Output of EAP 5.1.2:
WARN [LdapLoginModule] Invalid or misspelled option: useObjectCredential
WARN [LdapExtLoginModule] Invalid or misspelled option: java.naming.referral
WARN [LdapExtLoginModule] Invalid or misspelled option: roleAttributeIsDN
