[PERDITION-USERS] managesieve: Fatal Error reading

Hi, I just compiled Perdition 1.19-rc4 on my Ubuntu 10.04 box. I also installed vanessa_adt 0.0.9, vanessa_socket 0.0.12 vanessa_logger 0.0.10 by compiling the the sources. I didn't use any Parameters on the ./configure / autogen.sh scripts. I did have libssl-dev and libmysqlclient-dev while compiling so TLS/SSL and MySQL Support has been compiled into perdition . The Imap Proxy seems to work fine, but everytime I try to log in using managesieve my MailClient (Squirrelmail) tells me that it cannot connect to the server. In the mail.err Log just shows up a single line: "Fatal Error reading authentication information from client" Any advise what to do is highly appreciated. Regards Ben
