[CTDB and GFS] some troubles joining domain

[Ignacio Coupeau]

I'm building a cluster with CTDB and GFS/SAN/LB with three RH5 IBM 
xSeries ~346
	cman-2.0.64-1.el5
	2.6.18-8.1.6.el5
	kmod-gfs-0.1.16-5.2.6.18_8.el5

The filesystems are gfs1 because we encountered some troubles with the 
gfs2 in our scenario.

The installation was fine (from Jun 26 10:45 CEST)
	rsync -avz samba.org::ftp/unpacked/samba_3_0_ctdb .
	rsync -avz samba.org::ftp/unpacked/ctdb .
	
Our plan is test the shares with users in the domain, so the smb.conf:
	...
	netbios name = [piedra|papel|tijera]
	workgroup = UNAV-PDC-01
	...
	security = domain
	password server = pdc10
	...
	clustering = yes
	idmap backend = tdb2
	private dir = /usr/local/etc/users_1/clu
	...

The three nodes have an new freshly account in the PDC (as matter of 
fact, we have about 3500 machines in the domain with LDAP so, this not 
the point).

The problem is that:
	bin/net rpc join
returns always, in all three machines: "Segmentation fault".
However, I think the account in the LDAP/PDC side are wrote well 
(sambaSamAccount, sambaNTPassword, sambaPwdLastSet, sambaSID et al).

Some help/idea/point/track?
Thanks in advance,

Ignacio
