Is there a reproducble test case? I did some testing with uid uniqueness plugin, and in that case the preop functionm sends the result, so even if you set the result text in the pblock it is ignored(becuase the result was already sent).

If I don't send the result from the preop function, then my client does receive my error text:

{{{
preop_modify(....)
...
...
errtext2 = slapi_ch_strdup("mark's error text");
slapi_pblock_set(pb, SLAPI_PB_RESULT_TEXT, errtext2);
slapi_pblock_set(pb, SLAPI_RESULT_CODE, &result);
//slapi_send_ldap_result(pb, result, 0, errtext1, 0, 0);
}}}

the uiduniqeness is BE_TXN_PREOP plugin, and if one of these fail the result message is set:

slapi_pblock_get(pb, SLAPI_PB_RESULT_TEXT, &ldap_result_message);

This is missing for SLAPI_PLUGIN_BE_PRE_MODIFY_FN
