       pluginviewer - list loadable SASL plugins and their properties


       pluginviewer   [-a]   [-s]   [-c]   [-b min=N,max=N]   [-e ssf=N,id=ID]
       [-m MECHS] [-x AUXPROP_MECH] [-f FLAGS] [-p PATH]


       pluginviewer can be used by a server administrator to troubleshoot SASL
       installations.   The  utility  can  list loadable (properly configured)
       client and server side plugins, as well as auxprop plugins.


       -a     List auxprop plugins.

       -s     List server authentication (SASL) plugins.

       -c     List client authentication (SASL) plugins.

       -b min=N1,max=N2
              List client authentication (SASL) plugins.  Strength of the SASL
              security layer in bits. min=N1 specifies the minumum strength to
              use (1 => integrity protection). max=N2  specifies  the  maximum
              strength  to  use.   Only SASL mechanisms which support security
              layer with strength M such that N1 <= M <= N2 will be shown.

       -e ssf=N,id=ID
              Assume that an external security layer  (e.g.  TLS)  with  N-bit
              strength  is  installed.   The ID is the authentication identity
              used by the external security layer.

       -m MECHS
              Limit listed SASL plugins to the  ones  included  in  the  MECHS
              (space separated) list.

              Limit   listed   auxprop  plugins  to  the  one  listed  in  the
              AUXPROP_MECHS (space separated) list.

       -f FLAGS
              Set security flags. FLAGS is a comma separated list  of  one  or
              more  of  the  following security flags: noplain (SASL mechanism
              doesn´t send  password  in  the  clear  during  authentication),
              noactive   (require  protection  from  active  attacks),  nodict
              (require mechanisms which are secure against passive  dictionary
              attacks),   forwardsec   (require   forward  secrecy),  passcred
              (require  mechanisms  that  can  delegate  client  credentials),
              maximum (require all security flags).

       -p PATH
              Specifies a colon-separated search path for plugins.
