Sorry for the inconvenience. We informed the sales guys to get aback to you asap.
Regarding the payment I could not help you, I'm sorry.
The second point, on the other hand, is easy to answer. You can move your i-doit instance as often as you like. As long as you follow the system requirements, there is nothing to stop you. We also provide instructions for moving an instance in our knowledge base. -> https://kb.i-doit.com/pages/viewpage.action?pageId=66355511
If you don't want do make other users able to see the passwords, you can change the permission and set up taht the users are not allowed to see the password category in general
(the following article will help to understand the authorization system in i-doit -> https://kb.i-doit.com/display/en/Rights+Management)
You can edit the category list to not show the password column.
the relations between objects are created based on the categories. The question is, how to you connect these objects?
If you want to assign a client to a person you need the categories contact assignment and the specific category person->assigned obejcts.
these two categores will establish an relation between the client object and the person object, if they have been assigned to each other via the categories.
wir haben zur Zeit ein technisches Problem mit dem Download-Manager auf i-doit.org und arbeiten daran, dies so schnell wie möglich zu beheben. Der Download steht aber auch auf Sourceforge bereit.
this is not possible because the object browser is only ment to select objects themselves. There are some (rare) exceptions where you have a "two-sided" object browser where you first select the object and then the specific attribute - but these are limited to certain use cases (for example licenses or ports).
you can explicitly say which object types a group can see, edit, etc.. In the following article you can find an example of CMDB permissions with short explanations. https://kb.i-doit.com/pages/viewpage.action?pageId=61014337
For example, you can set the "Object(s) of type" right so that all but a few selected object types are hidden.
is the user still a member of a group that grants permissions? New permissions do not take effect immediately. Either the user has to wait a bit or you clear the cache in i-doit. (Administration -> System tools -> Cache / Databases -> Clear complete cache)
