select() does not like file descriptors larger then 1024 and sssd should avoid using select() especially in client code.

This can cause crashes in client apps on very busy systems using large numbers of file descriptors.

To check if select() is used the following call can be used

nm -D libnss_sss.so | grep select

if the output looks like 'U select' the select() is still used. If the output is empty select() isn't used anymore.
