Static Groups & Roles

Dynamic Groups & Roles

Reasons to use

  • The group membership is relatively stable.
  • The group membership changes frequently
  • Groups have large numbers of members

Advantages

  • Allows use of static roles
  • Allows use of dynamic roles
  • Easy to maintain (no need to add or delete members from groups)
  • No restriction on the number of members

Disadvantages

  • Hard to maintain (need to manually add and delete members from groups)
  • Update time increases as the number of group members increases
  • Data size may increase if the number of groups is very high and entries are included in many groups (due to members being listed many times)
  • Performance may decrease if the number of groups is very high (due to high number of group evaluations)
  • Applications cannot query group membership directly (instead, applications can read the group entry, and then search the members)
