RE: access violation in slapd (userCerficate search) (ITS#2004)

[sim@x509.ru]

The same problem is in version 2.1.3. So I add next strings to source:

slapd/ad.c:
....
	/* check for language tags */
	//sim: try to avoid access violation
	if (!super->ad_lang.bv_len)
		return 1;
....
to avoid access violation right now, and I would wait for version 2.1.4
to fix this error completely.

Thank you for response,
