Hi,
Thank you for your reply.
It is not so obvious to me. The bug report does not mention a segmentation
fault, but an excessive amount of time to fetch all groups.
the ticket also mentions this condition : enumerate = true , who is not
fulfilled in my case.

My config is the following :
/etc/sssd/sssd.conf : [sssd] services = nss, pam, ifp domains = ECCM.LAN
[pam] pam_verbosity = 2 offline_credentials_expiration = 0
/etc/sssd/conf.d/01_ECCM_LAN.conf [domain/ECCM.LAN] debug_level = 10
id_provider = proxy
proxy_lib_name=files
auth_provider = krb5 krb5_server = DebianCubox.eccm.lan krb5_realm =
ECCM.LAN krb5_validate = true krb5_ccachedir = /var/tmp krb5_keytab =
/etc/krb5.keytab krb5_store_password_if_offline = true
cache_credentials = true
