Hi, Iam looking for the schema files which includes the objectclass: mailGroup. I need this for alias ldap maps in conjunction with sendmail 8.11. Iam using openldap 2.0.7. Advices would be really great. Thomas - Thomas Heil Student zentrale EDV Umweltforschungszentrum Leipzig / Halle E-mail: heil@rz.ufz.de -
