Thanks Dan, > To make sure that the ldapdb plugin is installed correctly: > # cat > /usr/lib/sasl2/pluginview.conf > # pluginviewer | grep ldapdb hermod:/# grep sasl /etc/imapd.conf | grep -v '^#' | grep -v '^\s*$' | sed 's/^sasl_//' > /usr/lib/sasl2/pluginviewer.conf hermod:/# saslpluginviewer -a Installed auxprop mechanisms are: ldapdb sasldb List of auxprop plugins follows Plugin "ldapdb" , API version: 4 supports store: yes Plugin "sasldb" , API version: 4 supports store: yes Didn't know this tool so far.

See 'man ldap.conf' for options that you can place in ldaprc. If you do choose to use starttls, you'll need to replace ldaps://hel.mgr with ldap://hel.mgr. I tried sasl_ldapdb_uri: ldap://hel.mgr sasl_ldapdb_starttls: try and it comes out the same; slapd logs a successful STARTTLS. I tried: sasl_ldapdb_rc: /etc/ldap/ldap.conf which yields sending short packages in both cases. This slapd debug output is from a STARTTLS variant: TLS: can't accept: A TLS packet with unexpected length was received.. connection_read(16): TLS accept failure error=-1 id=8, closing connection_closing: readying conn=8 sd=16 for close connection_close: conn=8 sd=16 conn=8 fd=16 closed (TLS negotiation failure) But still imtest fails with "failure: prot layer failure". There is no activity in slapd before the password is entered in imtest. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
