[Dovecot] Problem using LDAP generating Userhome

[Thorsten Habich]

Hi there,
I'm trying to let dovecot generate the userhome directory dynamicly via 
user_attr.
If "uid" is returned from LDAP before "mail" everything is fine, but if 
"mail" is delivered
before "uid" the localpart of the mailaddress is used in home path.

e.g.:
Mail: testuser at domain.de
UID : test123

sometimes home is /mail/store/testuser and sometimes /mail/store/test123 
depending
on the order the ldap server replies.

I'm currently using version 1.2.7 of dovecot in testing and 1.1.6 in 
production. Both have
the same "bug".

Mails are stored on nfs, indexes are stored local.

This is my dovecot-ldap.conf configuration:

pass_filter = 
(|(&(objectClass=mailRecipient)(mail=%u))(&(objectClass=mailRecipient)(mailalternateAddress=%u))(&(objectClass=mailRecipient)(uid=%n)))
pass_attrs = 
uid=user,userPassword=password,mailMessageStore=home=%$/telefonica.de/%Ln,mailFilterStore=sieve_dir=%$/telefonica.de/%Ln
user_filter = 
(|(&(objectClass=mailRecipient)(mail=%u))(&(objectClass=mailRecipient)(mailalternateAddress=%u))(&(objectClass=mailRecipient)(uid=%n)))
user_attrs = 
uid=user,mailMessageStore=home=%$/telefonica.de/%Ln,mailFilterStore=sieve_dir=%$/telefonica.de/%Ln

The filter needs to be that way, because you need to be able to 
authenticate by uid or mailaddress.



And the dovecot -n output:
