\fBsasl_checkapop\fP  will  check  an APOP challenge/response.
APOP is an optional POP3 (\fI\%RFC 1939\fP) authentication command
which  uses  a  shared  secret (password). The password is
stored in the SASL secrets database.  For  information  on
the  SASL  shared secrets database see the System Administrators Guide\&.
.sp
If  called  with  a  NULL challenge, sasl_checkapop() will
check to see if the APOP mechanism is enabled.
.UNINDENT
