๐Ÿง About

Active Directory is a crucial part of many Information Systems as it manages both authentication and access management.

In this article, we'll focus on Active Directory group management analysis.

With this data, we are now able to :

  • ๐Ÿ“ Produce classification
  • ๐Ÿ”ฎ Make predictions
  • ๐Ÿ•ธ๏ธ Cross checking with third party identity management services

๐Ÿ”ญ Further with groups

We will link these datas (ie. relationships) on top of our our digital identity management, see below:

๐Ÿ’ก Group tuning & Minimum spanning tree

Having large set of groups has impacts on performances. Getting this data as a graph makes it possible to use graph algorithms to see if we can improve group assignment design thanks to Minimum spanning tree.

โš–๏ธ Member & Guest accounts

Guest users have default restricted directory permissions. They can manage their own profile, change their own password, and retrieve some information about other users, groups, and apps. However, they can't read all directory information. B2B guest users are not supported in Microsoft Teams shared channels.

Let's see how they are implemented:

// Groupes dont les 2 agents et les 2 guests du GLIA sont membres
MATCH (a:AD_agent {name:"3004XXX"})-[ia:IS_MEMBER_OF]->(g:AD_group)
<-[ig:IS_MEMBER_OF]-(b:AD_agent {name:"2999XXX"})
OPTIONAL MATCH (gu:AD_guest {name:"pXXX"})-[ip:IS_MEMBER_OF]->(g)
OPTIONAL MATCH (gue:AD_guest {name:"dXXX"})-[id:IS_MEMBER_OF]->(g)
RETURN a,g,b,gu,gue,ia,ig,ip,id
