Description

When the user has an LDAP server which enforces strict pagination (e.g.: olcSizeLimit
http://www.openldap.org/doc/admin24/limits.html set to 50)

and the user sets the following properties in usersync configs to comply with the server

ranger.usersync.pagedresultsenabled=true
ranger.usersync.pagedresultssize=50

paging happens only once according to the user specified pagedresultssize, then continues to paginate by the default pagination limit of 500 https://github.com/apache/ranger/blob/master/ugsync/src/main/java/org/apache/ranger/ldapusersync/process/LdapUserGroupBuilder.java#L57
