Map SASL principals to DNs for ACI validation
---------------------------------------------

                 Key: DIRSERVER-1453
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1453
             Project: Directory ApacheDS
          Issue Type: New Feature
            Reporter: Aaron J Angel


SASL authentication is not useful when using access control entries for authorization.  Access
control is based on a user's DN, but SASL principals/userIDs do not appear to be automatically
mapped to the appropriate user's DN.  For example, if I authentication using GSSAPI as the
user 'aKrbUser', whose credentials are stored in entry uid=aKrbUser,dc=example,dc=com, the
user should be authenticated to the directory and mapped to uid=aKrbUser,dc=example,dc=com
for access control validation.

See OpenLDAP's sasl-regexp parameter in slapd.conf for reference.  Example:

sasl-regexp cn=(.*),cn=example.com,cn=gssapi,cn=auth ldap:///dc=example,dc=com??sub?(uid=$1)

In OpenLDAP, the above line would search the directory context dc=example,dc=com for an entry
where the uid attribute value matches the GSSAPI user ID and assign assign the entry's DN
as the binddn.
