Thanks to Stephane Bortzmeyer ! His reply has solved my autofs-ldap problem !! Yes it has nothing to do with that topic but it was also an ACL problem.
Yes, "numEntries: 1" like with the anonymous user. The ACL for the super-user and for anonymous is:
access to * by dn="cn=admin,dc=eureg,dc=eu" write by * read
best regards,
