Hi,
I don't remember the details of your setup, below works for 4.2.b, 4.2.c.
1. are your selected AD users actually synchronized into alfresco so that they're now actually also alfresco users? I would check this by:
A. browse to http(s)://[youralfrescodomain]/alfresco
B. login as admin
C. click on the Administration console icon (beside the icon that looks like a person with a notepad and items on it).
D. click on Manage System Users and Show All
you should see your AD users there (also users created inside alfresco). if that doesn't work (it should, but not
sure what happens if lucene or solr is totally broken), you could look in "Company Home"/"User Homes" and see if
the user home directories were created there. if you can't search for the AD users and their user directories aren't
there then I don't think the AD users were imported. check your alfresco.log for ldap sync notifications/warnings/errors.
2. for any given site,
A. if you're the site manager (or an alfresco admin), you can add persons or groups as additional
site managers. go to /share and manage Users and Groups | Groups. For any given site you'll notice a
group for the site (e.g., the training-site might have the folowing groups (site_training-site,
site_training-site_SiteManager, and so on for SiteCollaborator, SiteContributor, SiteConsumer).
B. click on the SiteManager group. You are now able to add individuals or groups to be site managers.
Hover on the icons at top-right of the second pane. The rightmost one is add user, the middle one
is add group. clicking on either of those will allow you to select groups or persons to add.
You can manage site managers either manually (adding persons to the site manager group or creating groups in alfresco, adding persons to those groups, and then adding the groups to the relevant site manager groups), or you can manage it half in AD/LDAP and half in alfresco.
1. create the site manager groups in LDAP. have alfresco import those LDAP groups into alfresco
2. in alfresco, after the groups have synced, add the relevant AD-imported groups as managers to their respective sites.
Moving forward, the method above of an alfresco administrator being able to add any person (usually him/herself) as a manager for a site is very useful. Sometimes current site managers are removed from LDAP (they move on to another job), they get auto-removed from alfresco at next sync, and sites are then left with no managers. the alfresco admin can use the method above to assign someone else as manager for the group.
