How to use regex-role-mapper to map similar roles from LDAP server

Issue

• Some customers with LDAP servers returning LDAP similar roles; need map to only one role name for the authorization process in their applications or the EAP management module.

For instance: LDAP returns roles for some users / applications such as: 'ADMIN', 'Admin', 'Administrator' (just to name a few) and all of them must be recognized as 'Admin'

• The modification of all those similar roles in the LDAP server is not an option, due to those are linked or set up to many applications / users which could be hundreds or thousands.
