Hi Cristian,

not for a struct ldb_dn, no. The ldb_dn struct contains a private
'linearized' string pointer that is a child of the ldb_dn. For a
ldb_dn structure to remain valid, it needs to keep that pointer, so it
isn't appropriate to steal it away. 

I think a copy is appropriate in most cases, except where the caller
knows the lifetime of the ldb_dn structure is at least as long as the
ldb_message. In that case copying the pointer is fine.

Cheers, Tridge
