[Samba] net rpc join aborts and segfaults in 3.0.20b

[Peter Bortas]

I'm trying to migrate a TAS PDC to Samba 3.0.20b on Solaris 9. Trying to use
the NT migration guide gets stopped pretty quickly at just trying to join
the domain:

---8<-----------------------------------------------------------------------------
bash-2.05# net rpc join -S fillager -W LIU -U admin
Password:

[2005/10/24 00:21:28, 0] utils/net_rpc_join.c:net_rpc_join_newstyle(175)
error opening lsa policy handle: NT_STATUS_UNSUCCESSFUL
Unable to join domain Segmentation Fault (core dumped)
---8<-----------------------------------------------------------------------------

Using and debuglevel above 0 prevents the segfault and prints a pretty
uninitialized-looking domainname instead:

---8<-----------------------------------------------------------------------------
bash-2.05# net rpc join -d 1 -S fillager -W LIU -U admin
[2005/10/24 00:37:41, 1] libsmb/cliconnect.c:cli_full_connection(1495)

Cannot connect to server (anonymously). Error was NT_STATUS_ACCESS_DENIED

error opening lsa policy handle: NT_STATUS_UNSUCCESSFUL
Unable to join domainÿÿC.
---8<-----------------------------------------------------------------------------

So the interesting question is it unable to open the "lsa policy handle"?
What can I do to debug this? The account is created on the PDC and none of
the around 1000 Windows NT4, 2000 and XP machines we have connected to this
system on the University seems to have any problem joining the domain.
