commit changeset:54a3d99a96d84b42f680da43c7f638009c0f64d4/389-ds-base

Bug Description: Dereferencing null variable "d".
There is no possibility that (rc > 0) && (d == NULL), but it's
safe to check if d is not NULL before assigning '\0' to *d.

Fix Description: add checking if "d" is NULL or not before
assigning '\0' to *d.
