Mailbox does not exists after login

[Matt .]

It seems that the mailbox for a user is not created after login.

I get this in a debug log:

[LIST] No results

I have read that cyrus should not be able to login when it doesn't
have the default domain from the ldap server.

My setup is:

ldap: dc=sub,dc=comp,dc=local

and my users have uid at domain.tld as their domainname.

in my ldap (ipa I have)

# kolab, config
dn: cn=kolab,cn=config
objectClass: top
objectClass: extensibleobject
cn: kolab

# example.org, kolab, config
dn: associateddomain=example.org,cn=kolab,cn=config
objectClass: top
objectClass: domainrelatedobject
objectClass: inetdomain
associatedDomain: dc=sub,dc=comp,dc=local
associatedDomain: example.org
inetDomainBaseDN: dc=sub,dc=comp,dc=local

Any idea on this ?
