Doc Text: |
When a persistent search (psearch) was launched by a bind user without sufficient permissions, the access permissions object in cache previously failed to reset to point the initial pblock structure to the permanent structure. As a consequence, the ACL plug-in could crash the server due to a missing pblock object. This update ensures that the initial pblock object is reset to the permanent pblock and prevents the server from crashing in this situation.
