Can't reproduce this anymore with any recent version.

the maintenance "emty trash-folder on every login doesn't need a 
confirmation. it seems, that the confirmation fails when checking the 
needed rights.

in other words: on every login in a new month, there comes a 
confirmation that asks me, if i want to delete old attachements. i 
have to confirm or cancel this action. while this question is not 
answered, there is no menu-sidebar on the left. only the small 
top-menu with help and logout.

now, i defined some user-groups in horde. no problem. all works fine. 
the groups are not the problem. after that, i tested the 
rights-management: i assigned all possible rights (show, read, edit 
and delete) for imp and for horde to a group xyz and added some users 
to this group.

all users of this group can use imp without any problems. but when the 
maintenance-confirmation-screen appears, the screens persists in a big 
white empty - only the small top-menu (help, logout) appears. the user 
cannot confirm the maintenance and without confirmation, it's not 
possible to use imp. seems, that the maintenance-confirmation ignores 
the assigned rights and will not be shown.

the groups are not the problem - the definition of rights makes 
trouble. but more rights that "show, read, edit, delete" cannot be 
set. and i set the rights to horde and to imp, too. without any success.

when i delete these rights, so that everyone has all rights, 
everything works fine.

You could use a maintenance like emptying trash folders and set it to 
run on every login. Beside that, just to be sure I get you right: this 
happens as soon as you start using groups, no matter what permissions 
you set?

i'm not sure, if this bug concers to IMP or the Horde-Base, but i've 
discovered the following problem (using imp4.0.4, horde3.0.6, php5.0.4 
and authorisation to a courier-imap-server):



i've defined a group for every module (horde-users, imp-users, ...) 
and assigned the rights show, read, edit and delete of each module to 
the concerning group. i added some users to different groups and 
everything works fine.



but when a new month starts, all modules were not usable after login. 
horde always loads the following url:

./login.php?url=%2Foffice%2Fservices%2Fmaintenance.php%3Fmodule%3Dimp%26amp%3Bdomaintenance%3D1



it seems, that horde tries to do imp's maintenance (e.g. delete old 
attachements...) but this fails.  while the maintenance is not done, 
it's not possible to load the menu or the imp-module. and while using 
groups and rights, the maintenance fails.  seems, that the 
permission-check fails. but the users have all possible rights (show, 
read, edit, delete) to horde and imp.

is this a bug or an misconfiguration?

it's not easy to reproduce cause i have to wait till next month for 
maintenance ;)
