Ok, thx for the infos. I also find some information a bout this two line in my config file
# adclient.cache.expires.group: 3600
# adclient.cache.expires.group.membership: 3600
This option are apparently not enable by default. But if the sync problem not come from the AD part. Would you think i should try to edit this to maybe accelerate the process ? Or centrify sync the ad faster enough by default (btw i haven't find infos about that).
Thx again for helping
