Using slapo-rwm can cause slapd to crash when the following conditions occur:
1. overlay rwm is used in slapd.conf before or within a database meta section. 2. The database meta configuration proxies request to a Windows Active Directory server. 3. An Active Directory User object is queried and contains a value of a single blank space in either the "homePhone" or "pager" attribute.
When the "overlay rwm" is removed from the configuration, the assertion does not occur.
