Subject: [PATCH] idviews: clear intermediate target DN in all cases
|
|
|
b090fc |
|
|
|
b090fc |
When processing a search request, slapi-nis attempts to detect an ID
|
|
|
b090fc |
View lookup. A target DN is modified by extracting an ID view name. This
|
|
|
b090fc |
temporary string is freed in the successful case but left unotouched if
|
|
|
b090fc |
ID View wasn't requested. As a result, small leaks on each search
|
|
|
b090fc |
request accumulate and a memory can get lost.
|
|
|
