[Dovecot] Strange quota problem

[Jan-Frode Myklebust]

I have a strange problems with quota on v2.0.14. We have an ldap user
directory, and all users should have a mailQuota defined there. My
problem is that some users gets the quota enforced, while others don't, 
and "doveadm user" doesn't seem to agree with "doveadm quota ge gett"

Ref:

	$ doveadm user janfrode at example.net
	userdb: janfrode at example.net
  		home      : /usr/local/atmail/users/j/a/janfrode at example.net
  		mailQuota : quota_rule=*:storage=2100000
	$ doveadm -f tab quota get -u janfrode at example.net
	Quota name	Type	Value	Limit	%
	UserQuota	STORAGE	760	1000000	0
	UserQuota	MESSAGE	62	-	0

Why limit 1000000 instead of 2100000 ?

	$ doveadm user omar at example.net
	userdb: omar at example.net
  		home      : /usr/local/atmail/users/o/m/omar at example.net
  		mailQuota : quota_rule=*:storage=1000000
	$ sudo doveadm -f tab quota get -u omar at example.net
	Quota name	Type	Value	Limit	%
	UserQuota	STORAGE	0	-	0
	UserQuota	MESSAGE	0	-	0

	$ doveadm user testkunde at example.net
	userdb: testkunde at example.net
  		home      : /usr/local/atmail/users/t/e/testkunde at example.net
  		mailQuota : quota_rule=*:storage=1000000
	$ doveadm -f tab quota get -u testkunde at example.net
	Quota name	Type	Value	Limit	%
	UserQuota	STORAGE	33918	-	0
	UserQuota	MESSAGE	137	-	0

Why no storage limit ?
