Hi

I have some news about that problems
i though it was solved because i configured the groups to follow an 
empty part of my ldap server.
I have configured the groups to read in the good part of my ldap server 
and the slow performance is back again.

There s someting strang by the way
on my machine i type
id doutrele
on the sssd_default.log i can read the following line
(Tue Jun 15 14:00:38 2010) [sssd[be[default]]] [be_get_account_info] 
(4): Got request for [4097][1][name=doutrele]
then a ton of lines where the system try to find of which group the user 
doutrele belong.
then i read
(Tue Jun 15 14:00:39 2010) [sssd[be[default]]] [ldb] (9): Entry not 
found (name=zou,cn=users,cn=default,cn=sysdb)
(Tue Jun 15 14:00:40 2010) [sssd[be[default]]] [sdap_save_groups_loop] 
(9): Group 5 processed!
(Tue Jun 15 14:00:40 2010) [sssd[be[default]]] [sdap_save_group_send] 
(7): Adding original DN 
[cn=CampusTMSP,ou=Group,ou=System,dc=int-evry,dc=fr] to attributes of 
[CampusTMSP].
(Tue Jun 15 14:00:40 2010) [sssd[be[default]]] [sdap_save_group_send] 
(7): Adding member users to group [CampusTMSP]

(Tue Jun 15 14:00:40 2010) [sssd[be[default]]] [sdap_save_group_send] 
(7): Adding member users to group [CampusTMSP]

he saved a lot of groups in the local cache and proceed the last group 
CampusTMSP
and i read that
(Tue Jun 15 14:00:42 2010) [sssd[be[default]]] [ldb] (9): Entry not 
found (name=zriouil,cn=users,cn=default,cn=sysdb)
(Tue Jun 15 14:00:42 2010) [sssd[be[default]]] [ldb] (9): Entry not 
found (name=zryouil,cn=users,cn=default,cn=sysdb)
(Tue Jun 15 14:02:32 2010) [sssd[be[default]]] [sdap_save_groups_loop] 
(9): Group 6 processed!

then it takes 1m50s to save the last group.
is there a way to speed up that process?


Thanks in advance for any help
