BTW, in some parts of cyrus.c, ld->ld_defconn is checked for the NULL
value before ld->ld_defconn->lconn_sasl_ctx is used. Should I do the
same here? FYI, I just added a check to the above code to 'return -1'
if ld->ld_defconn == NULL and I get a response from slapd (same
response as when using -H ldap://). Considering that
ldap_pvt_tls_start in tls.c discards the return value of
ldap_int_sasl_external, this is probably ok.

Should all uses of ld->ld_defconn->lconn_sasl_ctx have a check for
'ld->ld_defconn == NULL'? There are a few other places where
ld->ld_defconn->lconn_sasl_ctx is used without testing ld->ld_defconn
for NULL.
