nscd: nss_ldap: could not search LDAP server - Server is unavailable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patrick,

I am still unable to figure out what is the cause for the clients to
time-out on LDAP connection. Is there nay performance tuning that I am
unaware of?

What is appropriate timelimit for search/bind/idle? To give some idea, we
roughly have ~300 users and 600 servers.

Is there a timeout settings in 389-ds?

Thanks,
Prashanth
