Retrieve LDAP data in Chunks using DBMS_LDAP

Question

Need help in getting the LDAP data in Chunks using the DBMS_LDAP. The reason being i have over 8000 records in the AD and it is configured that i cannot retrieve more than 1000 at a stretch.
The AD administrator had given me an option of fetching it based on the pagesize which they use on AD.
Dim DirSearcher As New DirectorySearcher()
DirSearcher.SearchRoot = New DirectoryEntry("LDAP://" & System.Environment.UserDomainName)
DirSearcher.Filter = "(&(objectclass=user)(objectcategory=person))"
DirSearcher.PageSize = 1000
Can we have something like this done in the DBMS_LDAP package to fetch the records in AD in chunks of 1000 records?

Answer 1

if there are more than 1000 entries which starts with a character, how will this solution work?You would have to incorporate one more loop (and so on, in case it still errors out):
  for c in ascii ('a') .. ascii ('z')
  loop
    for d in ascii ('a') .. ascii ('z')
    loop
      l_retval :=
        dbms_ldap.search_s (ld         => ld
                            base       => base,
                            scope      => dbms_ldap.scope_subtree,
                            filter     => '(&(objectCategory=person)(objectClass=user)(sAMAccountName=' || chr (c) || chr(d) || '*))',
                            attrs      => attrs,
                            attronly   => 0,
                            res        => res
    end loop; 
  end loop; 
...Not nice I know, but it seems to be the only way to avoid »ORA-31202: DBMS_LDAP: LDAP client/server error: Sizelimit exceeded«.
