> Add posixGroups support for LDAP group lookup. The current implementation works only with groupOfNames. 
> posixGroups have "memberUid" attribute which is different from "member" attribute, and when we set main.ldapRealm.memberAttribute equal to "memberUid", this line (306) in org.apache.hadoop.gateway.shirorealm.KnoxLdapRealm.java:
> {noformat}
> if (userLdapDn.equals(new LdapName(attrValue)))
> {noformat}
> will generate an InvalidNameException because "memberUid" is just an id and not formatted according to the rules defined in RFC 2253.
> To fix this, we need to just test if the group is a posixGroup and then update attrValue by adding memberAttributeValuePrefix and memberAttributeValueSuffix
