PosixGroups

[Openldap - Sadesi <openldap.sadesi@juntadeandalucia.es>]

Hello alls!!!

i want to introduce the posixgroups in my ldap.
i have one application that needs validate the users when log in.

anybody knows documents (how to) that explain the use of posixGroups 
(the standar)
i had thought an DIT's architecture like this:
o=myorg,c=es
- ou=users
  - cn=user1
    +userpassword=ppp
   - cn=user2
     +userpassword=ooo
- ou=application
 - cn=application1-adms
     +memberUid=user1
     +memberUid=user2
  
where - are son node and + are attributes
my application to validate user1 will make the next steps
   1. search basedn="cn=application1-adms,ou=application,o=myorg,c=es" 
scope=sub  filter=(memberUid=user1)
    2. bind to dn="cn=user1,ou=users,o=myorg,c=es"

are this steps the usually sequence?

TIA
