In Table A.16. Ldap Module Options there is option roleNameAttributeID with "group" default value, but default value is "name", it should be changed. Same update is needed in roleNameAttributeID in table A.18. LdapExtended Module Options.
Moving to ON_QA. The changes should be available for review on the documentation stage within an hour or so from this comment. http://documentation-devel.engineering.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/
Verified on stage.
