So NetApp is starting to push Data ONTAP 8.1 running in Cluster Mode as the Next Big Thing in storage technology because among other things is brings scale-out to our already industry-leading storage management technology.

Part of the future is NFSv4, which as I said in an earlier post requires some level of username to uid mapping functionality (though this is actually an option in Data ONTAP 8.1) to work right, so since I'm a Linux geek and I wanted NFSv4 working on my simulator environment I decided to get LDAP working.

It is not nearly as straightforward as it was in 7-mode but it is possible.

  1. Setup the NFSv4 domain to match your current environment:
    piper::*> nfs modify -vserver test-vserver -v4-id-domain localdomain
    piper::*> nfs show -vserver test-vserver -instance
    Vserver: test-vserver
     General NFS Access: true
     RPC GSS Context Cache High Water Mark: 0
     RPC GSS Context Idle: 0
     NFS v2: disabled
     NFS v3: enabled
     NFS v4.0: enabled
     NFSv4 ID Mapping Domain: localdomain
  1. Create a LDAP client configuration:
    piper::*> vserver services ldap client create -client-config test-ldap -servers -min-bind-level simple -bind-dn cn=nis,dc=ub3rgeek,dc=net -bind-password password -base-dn dc=ub3rgeek,dc=net -user-dn ou=users,dc=ub3rgeek,dc=net -group-dn ou=groups,dc=ub3rgeek,dc=net
    piper::*> vserver services ldap client show -instance
    Client Configuration Name: test-ldap
     LDAP Server List:
     Active Directory Domain: -
     Preferred Active Directory Servers: -
     Bind Using the Vserver's CIFS Credentials: false
     Schema Template: RFC-2307
     LDAP Server Port: 389
     Query Timeout (sec): 3
     Minimum Bind Authentication Level: simple
     Bind DN (User): cn=nis,dc=ub3rgeek,dc=net
     Base DN: dc=ub3rgeek,dc=net
     Base Search Scope: subtree
     User DN: ou=users,dc=ub3rgeek,dc=net
     User Search Scope: subtree
     Group DN: ou=groups,dc=ub3rgeek,dc=net
     Group Search Scope: subtree
     Netgroup DN: -
     Netgroup Search Scope: subtree
     1 entry was displayed.

3. Create the LDAP server.

    piper::*> vserver services ldap create -vserver test-vserver -client-config test-ldap
  1. Enable LDAP for NSS lookups on your Vserver
    piper::> vserver modify -vserver test-vserver -ns-switch ldap,file
    piper::*> vserver show -vserver test-vserver -instance

    Vserver: test-vserver
     Vserver Type: cluster
     Vserver UUID: 13e83952-b56d-11e1-b2c3-123478563412
     Root Volume: testvserver
     Aggregate: aggr01_a
     Name Service Switch: ldap, file
     Name Mapping Switch: file
     NIS Domain: -
     Root Volume Security Style: unix
     LDAP Client: internal
     Language: C
     Snapshot Policy: default
     Anti-Virus On-Access Policy: default
     Quota Policy: default
     List of Aggregates Assigned: -
     Limit on Maximum Number of Volumes allowed: unlimited
     Vserver Admin State: running
     Allowed Protocols: nfs
     Disallowed Protocols: cifs, fcp, iscsi
     Protocol Services use Data LIFs: true

Now you should be able to mount your export!

apollo 20:32:34 ~ (2253)$ mount
 ...snip... on /mnt type nfs (rw,vers=4,addr=,clientaddr=

And if you look, it should resolve your usernames!

apollo 20:49:12 ~ (2254)$ ls -la /mnt
total 391824
drwxrwxrwx  3 nobody   nogroup      4096 Jun 15 20:00 .
drwxr-xr-x 25 root     root         4096 Mar 23 16:10 ..
