RE: Host based authentication using OpenLDAP


I follow your conversation because I have to do the same thing, so I would like to add hosts in my openldap but I don't succeed

My add.ldif

dn: cn=hostlab,ou=hosts,dc=netplus,dc=fr
objectClass: top
objectClass: authorizedServiceObject
objectClass: ipHost
cn: hostlab
authorizedService: sshd
authorizedService: ftp

my command

# ldapadd -x -D "cn=manager,dc=netplus,dc=fr" -w **** -f add.ldif
adding new entry "cn=hostlab,ou=hosts,dc=netplus,dc=fr"
ldapadd: Object class violation (65)
        additional info: no structural object class provided

What is the problem ? in my phpldapadmin I have this message:

Importation au format LDIF
Impossible d'ajouter un objet : cn=hostlab,ou=hosts,dc=netplus,dc=fr
You tried to perform an operation that would cause an undefined attribute to exist or that would remove a required attribute, given the current list of ObjectClasses. This can also occur if you do not specify a structural objectClass when creating an entry, or if you specify more than one structural objectClass.

Maybe I had to post in a new message, sorry if I'm wrong.

And fyi, here's an example... For a given host:

dn: cn=hostX,ou=hosts,dc=example,dc=com
objectClass: ipHost
objectClass: authorizedServiceObject
cn: hostX
authorizedService: sshd
authorizedService: ftp

you use the authorizedService attribute to list the PAM services that are
available. Then you set ACLs to control who can access each service, like so:

access to dn.subtree=ou=hosts,dc=example,dc=com
   attrs=authorizedService val.exact=sshd
   by group.exact="cn=admins,ou=groups,dc=example,dc=com" write
   by peername.ip= read
   by * search

The overlay performs a Compare operation to check for the required service, so
if you deny Compare access to a particular service, then users aren't allowed
to use that service.
