[Dovecot] strange problem receiving mails

[deconya]

Hi guys

Im viewing how to repair a problem using a postfix platform with openldap
and dovecot. This is the problem:

-When I create a new user inside openldap with mail account appears
correctly inside ldap but when I access first time appears inside
/var/spool/dovecot/ the folder of account bad. Not appears the name of uid,
appears the name of user mail, for ex:

drwx------   5 exemple             Domain Users      4,0K 2011-03-04 13:28
exemple
drwx------   9 exemple             Domain Users      4,0K 2011-03-04 13:29
exemple.usermail
