[Dovecot] Expire plugin in chkpw-wrapper.sh script

[Jose Luis Marin Perez]

Hi timo,

This is the error that comes when adding userdb checkpassword 

dovecot: Oct 16 10:13:53 Fatal: auth(default): Unknown userdb driver 'checkpassword' (typo, or Dovecot was built without support for it? Check with dovecot --build-options)
dovecot: Oct 16 10:13:53 Fatal: Auth process died too early - shutting down

 Running 

 dovecot - build-options 

 Build options: epoll ioloop = notify = dnotify ipv6 openssl 
 Mail Storage: mbox maildir raw cydir dbox 
 SQL drivers: mysql 
 Passdb: vpopmail sql checkpassword 
 Userdb: vpopmail sql prefetch 

 Checkpassword not compiled for userdb. 

 Excuse the dumb question, with that option adding to compile dovecot userdb checkpassword? 

 No information found about this. 

 Thanks

Jose Luis
