PTLOADER and LDAP for authorization and ptloader dies

[Sebas PRE]

This is my intallation:
- Red Hat Enterprise 3
- imapd-2.2.12 or imapd-2.3.3 (I tested both)
- cyrus-sasl-2.1.15

I have in 'cyrus.conf':

  ptloader      cmd="ptloader" listen="/u01/config/ptclient/ptsock" prefork=1


in the file 'imapd.conf':

# LDAP PTLOADER
auth_mech: pts
pts_module: ldap
ptloader_sock: /u01/config/ptclient/ptsock
ptscache_db: skiplist
ptscache_timeout: 10800
ldap_sasl: 0
ldap_uri: ldap://ldapserver:port/
ldap_bind_dn: cn=adminuser
ldap_password: adminpass
ldap_base: ou=main,dc=org
ldap_scope: sub
ldap_version: 3
ldap_size_limit: 0

and in 'saslauthd.conf'
ldap_servers: ldap://ldapserver:port/
ldap_search_base: ou=main,dc=org
ldap_bind_dn: cn=adminuser
ldap_password: adminpass


When I run 'master' process I cann´t connect to IMAP and I obtain the typical
bad password error. Now I see this in my cyrus.log:

Can anybody help me?
