Hi.
Excuse my English.
I have a huge problem here.
I have the following scenario:
- Gentoo
- Kernel 2.6.31
- Samba 3.0.37
- OpenLDAP
- Samba + OpelLDAP as a PDC
- 600 users
- 20 groups
- 30 simultaneous users in the highest scenario
- It's a very small scenario anyway
Everything works fine, the times to copy files are fine, no delay at all!
But one application, a Delphi + Paradox application, spends more than 5
minutes to open and to do each possible operation.
That application doesn't has any network user, it has its own user
"database" and it's only an *.exe file in a share.
The network is ok, only five users connected and doing nothing.
I've blamed the application at the first time, but I have too a testing
Samba system running in an Slackware, without OpenLDAP, and when I've tried
with that, the application have run fine.
I'm going crazy here...
I've checked my kernel, smb.conf, ldap.conf, slapd.conf, everything seems
ok.
So, I'll put here all my configuration files, sorry if it is an abuse.
Can someone help me? I'm desperate...
