maximum NTLM_AUTH/Winbind concurrent request

[Tharanga Abeyseela (RGA)]

I was trying to put winbind max clients directive in smb.conf. but testparam doesn’t like it. (3.5.6).
Is there any limitations to WINBINDD_MAX_CLIENTS in include/local.h ? I increased that to 2000. Can it cause any impact on performance ? memory allocation issues etc ?

Thanks,
Tharanga Abeyseela

No. 3.6 only, or else you can change (from memory) the
WINBINDD_MAX_CLIENTS define manually in the source code yourself.

Yes.

But note Volker's warning that it will just help ensure there is a
queue, rather than processing the operations in parallel.  Patches to
make things actually parallel are apparently being developed, which will
make a real difference here once finished.
