How many users can I import from my AD?

Simone Eusebi Lv1Posted Feb-27-2026 19:59

Hi all,
my infrastructure is composed by HCI+VDC+SCP.
VDC is 5.9.6EN. I have setup it in order to accept users from an external LDAP/Radius.
My LDAP is correctly configured and I can navigate to the tree-structure of it.
I need now to import users but they are a lot (around  250k).
Is it possible or there is a hard limit?

Thank you,
best regards

Simone

Enter your mobile phone number and company name for better service. Go

There is no small hard-coded limit like 10k or 50k, but:

Importing 250k users directly into VDC is NOT recommended.
Performance, sync time, login delay, and database load become serious concerns.
Best practice is to import by OU or Security Group, not entire directory.
