    Bug Description: Should not attempt to pop SASL IO layer if not 
using SASL IO
    Reviewed by: ???
    Fix Description: Before attempting to pop the SASL IO layer from the 
prfd,
    first make sure we are using sasl IO, the prfd is not NULL, and the prfd
    has a SASL IO layer on it.
    This also fixes a bug with setting nsslapd-localhost in the 
bootstrap code -
    if you are using a system that does not have DNS configured 
correctly, you
    may want to force the SASL code to use the nsslapd-localhost for the 
FQDN.
    Platforms tested: RHEL5 x86_64
    Flag Day: no
    Doc impact: no
