[Samba] nsswitch segfaults with Samba 3.0.21 on Solaris 9

[J S]

I've built Samba 3.0.21 with Kerb ADS, NSS, Winbind and PAM support  on
Solaris 9 using gcc 3.3.2.

  I'm able to compile and install and authentication works fine - I can
query and authenticate with AD, but when I su, passwd or some other local
auth Solaris command the command segfaults. This even happens if a valid
user is in any of the databases previous in the search pattern to winbind.


[root at smb01:/export/build/smb321/lib]#  su - bob

I tried to get clever with nsswitch, and still got the same errors. :

#passwd:     files ldap winbind [NOTFOUND=return]
#passwd:     files ldap [SUCCESS=return] winbind
#group:      files ldap [SUCCESS=return] winbind
