Solution
You simply do the following:
- Set the Base DN in the SpiraTeam LDAP Configuration Page to Base DN #1.
- Import the desired users from Base DN #1
- Set the Base DN in the SpiraTeam LDAP Configuration Page to Base DN #2
- Import the desired users from Base DN #3
- (Repeat for additional Base DNs)
This works because SpiraTeam associates each user with the full LDAP DN path regardless of where it was imported from.
