Fixed In Version: 389-ds-base-
Doc Type: Bug Fix
Doc Text:
.Directory Server now processes new operations only after a previous SASL bind fully initialized the connection During a bind using the Simple Authentication and Security Layer (SASL) framework, Directory Server initializes a set of callback functions. Previously, if Directory Server received an additional operation on the same connection during a SASL bind, this operation could access and use the callback functions even if they were not fully initialized. Consequently, the Directory Server instance terminated unexpectedly. With this update, the server prevents operations from accessing and using the callback structure until the previous SASL bind is successfully initialized. As a result, Directory Server no longer crashes in this situation.
