It looks like in pdb_ldap.c this fragment might be NULL:
static NTSTATUS ldapsam_getsampwnam(struct pdb_methods *my_methods, SAM_ACCOUNT *user, const char *sname)
{
NTSTATUS ret = NT_STATUS_UNSUCCESSFUL;
struct ldapsam_privates *ldap_state = (struct ldapsam_privates *)my_methods->private_data;
LDAPMessage *result = NULL;
LDAPMessage *entry = NULL;
int count;
char ** attr_list;
int rc;
attr_list = get_userattr_list( ldap_state->schema_ver );
append_attr(&attr_list, get_userattr_key2string(ldap_state->schema_ver,LDAP_ATTR_MOD_TIMESTAMP));
**************************************************************************
I don't know why. The code should really contain an assertion and fail
gracefully if get_userattr_key2string returns NULL.
OTOH, it might be a LDAP-problem (either bug or you didn't setup the database correctly).
On a brighter note, this isn't really a FreeBSD-specific issue, I'd guess #)
Can you please post this problem (feel free to include my interpretation!) to the
Samba-bugtracker? Don't forget to include the *full* gdb output. I'm going to suspend
this PR until we have feedback from the Samba crowd.
Cheers,
Volker
