Dear List,

I have CentOS 5.5 64bit (fully updated) , Samba3 3.5.5-43.el5 (SerNETSamba) , openldap-2.3.43-12.el5_5.2 , nss_ldap-253-25.el5 .My Problem is , If I login to the domain and run a program from the Samba3 Server it's slow , if I login from this same machine but this time to the local account, and then I go to the Samba3 server specify domain admin password when asked for it(only once,when accessing the desired share) and run the same program I'm 2-3x times faster. I've googled a bit, and found another guy was having speed problems when runing programs on a Samba3 server with ldap backend. But I must admit I'm no Openldap expert, if you can please take a look at my config and tell me what is wrong with it, it's probably the ldap part... what I did try sofar stoped openldap , and did a slapindex, and started it again but no help.

Bellow are my config files :

/etc/samba/smb.conf
