Fixed In Version: 389-ds-base-
Doc Type: Bug Fix
Doc Text:
.Directory Server instance names can now have up to 103 characters When an LDAP client establishes a connection to Directory Server, the server stores information related to the client address in a local buffer. Previously, the size of this buffer was too small to store an LDAPI path name longer than 46 characters. For example, this is the case if name of the Directory Server instance is too long. As a consequence, the server terminated unexpectedly due to an buffer overflow. This update increases the buffer size to the maximum size the Netscape Portable Runtime (NSPR) library supports for the path name. As a result, Directory Server no longer crashes in the mentioned scenario. Note that due to the limitation in the NSPR library, an instance name can be maximum 103 characters.
