[Dovecot] Dovecot Ldap Logs

[Proskurin Kirill]

Hello all!

One question about ldap.
In my logs im see this:

Info: auth(default): ldap(sysadmin at domain.off,172.16.1.80): user search: 
base=dc=CAS scope=subtree 
filter=(&(objectClass=mailUser)(mail=sysadmin at domain.off)) fields=(all)

Info: auth(default): ldap(sysadmin at domain.off,172.16.1.80): result: 
accountStatus(?unknown?)= cn(?unknown?)= givenName(?unknown?)= 
initials(?unknown?)= l(?unknown?)= o(?unknown?)= objectClass(?unknown?)= 
telephoneNumber(?unknown?)= sn(?unknown?)= title(?unknown?)= 
uid(?unknown?)= userPassword(?unknown?)= mail(?unknown?)=

---

What is that mean? And how can im get a rid of this?
