Ldap sync schedule

Hello, what is the default LDAP sync schedule ? Is there a way to set it to a custom value?
I set up the LDAP system a few days ago and everything worked well, but this morning I added 2 new users in LDAP and I still can not see them in Nextcloud after six hours.

I am using Nextcloud 10.0.3 on Ubuntu 16.

you should see them within 10min, otherwise they dont satisfy your user filter or user base tree.
