i need posixAccount & posixGroup from
etc/openldap/schema/nis.schema

my database workes on openldap 1.2.11 (5000 user+ 200 groups+)
i tried it with openldap 2.0.1 and it worked like openldap 1.2.11 without
indexes

in slapd.conf i couldn't set
index           gidNumber                               pres,eq
index           uidNumber                               pres,eq

so i had 2 use 
index           gidNumber                               pres
index           uidNumber                               pres

the schema/nis.schema: EQUALITY integerMatch is only used on 
gidNumber,uidNumber. Non of the other attributes in the databese uses 
the integerMatch

the clients use linux redhat 6.2 with pam ldap & nss ldap from www.padl.com
