I am testing sssd and the pam and nss package on Ubuntu here at the
university, and ran into unexpected behaviour. sssd_be uses 100% CPU
most of the time, and top report that its virtual size is 244 MB and
its resident size is 152 MB. I've configured sssd to use LDAP as a
directory and as the authentication method.
The university have a lot of users and groups, and I wonder if this is
why the process is so big and use so much CPU. How well do sssd
scale? Can it handle a directory with 100 000 users and 10 000
