Title: #5300: ad: use parallel cldap ping for site discovery
sumit-bose commented:
"""
Hi,
maybe there should be some limit in the for-loop so that SSSD does not accidentally tries
to ping hundreds of DC in a larger AD environment.
adcli implements a scheme described in
https://winprotocoldoc.blob.core.windows.net/productionwindowsarchives/Wi...
section 5.4.5.3 where first 5 DC are pinged with a 0.4s timeout, then the next 5 are
pinged with a 0.2s timeout and finally all other with a timeout of 0.1s. Unfortunately I
haven't found any newer document how Windows clients are doing CLDAP pings.
bye,
Sumit
