Re: ldap_simple_bind blocks in Open Mode when the DS is in hang state

it does look like NSS is not respecting timeout you set with
PRLDAP_OPT_IO_MAX_TIMEOUT. it might be the case that it only
would apply it on send operation but not on receive. since
receive and poll there are invoked directly by NSS itself i
would expect it to respect the timeout specified on original
operation [we invoke] in its internally spawn operations as
well however it doesnt seem to be the case here. i recommend
asking on NSS list about that.
