> 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
