Odd error when trying to run commands in both ways.

believe or not! NIM again :-(
Here I go.

First, I create the client-MACHINE on the NIM.

On the NIM server:
bibmdes_cont:
   class          = machines
   type           = standalone
   connect        = nimsh
   platform       = chrp
   netboot_kernel = 64
   if1            = ent-Network1 bibmdes_cont 0
   cable_type1    = N/A
   Cstate         = ready for a NIM operation
   prev_state     = ready for a NIM operation
   Mstate         = currently running

ent-Network1:
   class      = networks
   type       = ent
   comments   = Generated during definition of bibmdes_cont
   Nstate     = ready for use
   prev_state = information is missing from this object's definition
   net_addr   = 172.17.32.80
   snm        = 255.255.255.240
   routing1   = default 172.17.32.94

Now, go to the client and setup nim.

On the client:
smitty nim
                                                        [Entry Fields]
* Machine Name                                       [bibmdes_cont]
* Primary Network Install Interface                  [en0]                                +
* Host Name of Network Install Master                [bibmnim]

  Hardware Platform Type                              chrp
  Kernel to use for Network Boot                     [64]                                 +
  Communication Protocol used by client              [nimsh]                              +
  Ethernet Interface Options
    Network Speed Setting                            []                                   +
    Network Duplex Setting                           []                                   +
  Comments                                           []


Setting up SSL
smitty nim_config_services
* Communication Protocol used by client              [nimsh]                              +

  NIM Service Handler Options
*   Enable Cryptographic Authentication              [enable]                             +
      for client communication?

Everythings looks OK, no error.

So, back to NIM, you can see the nimsh-secure protocol.

On the NIM:
bibmdes_cont:
   class          = machines
   type           = standalone
   connect        = nimsh (secure)
   platform       = chrp
   netboot_kernel = 64
   if1            = ent-Network1 bibmdes_cont 0
   cable_type1    = N/A
   Cstate         = ready for a NIM operation
   prev_state     = ready for a NIM operation
   Mstate         = currently running
   cpuid          = 0009EACAD400

Trying to update_all from the client:
smitty nim
 Install and Update Software
 Update Installed Software to Latest Level (Update All)
 On the BOX (Select the LPP_SOURCE containing the install image) you can see all resources got them from the NIM, so I select the LPP resource:
  ENTER
  ENTER
 
 BUT get this error:
 
 Command: failed        stdout: yes           stderr: no

Before command completion, additional instructions may appear below.

0042-001 nimclient: processing error encountered on "master":
   0042-001 nim: processing error encountered on "master":
   0042-006 m_cust: (From_Master) connect Error 0

        0042-404 nconn: Error connecting to SSL object.
        0042-406 nconn: Error verifying SSL object after connection.
nconn: ð}
: Error 0

I did another test from the NIM, and get the same error.

Any idea why?

Thanks.
