glibc's getgrouplist(3) implementation retrieves all groups and filters for groups containing the specified user.

When /etc/group contains many groups this takes a while. glibc's behaviour can be overridden in /etc/nsswitch.conf (using the initgroups database).

It'd be useful if libnss-cache implemented getgrouplist(3) using an index from user to list of groups.

I´m configuring nsscache for caching ldap credentials on /etc/passwd.cache and then make the magic with libnss-cache.

On ubuntu i´m not having any kind of problem, but on centos it doesn´t look like getent passwd is getting the user list from the cached passwd.

Could it be caused by the location of libnss_cache.so.2.0? i tried moving it to /usr/lib/, /usr/lib64/ and /usr/lib64/nss and no luck so far
Anyone has any experience making it work on centOS 7?

I tried to find something using strace in front of the nsscache command but can´t find nothing of value.

Cheers

Unless I'm totally overlooking something, this library doesn't appear to be configured properly for Debian multiarch support. See https://wiki.debian.org/Multiarch/Implementation

make check fails for a variety of reasons including that it depends on gen_cache.py which isn't in this VCS.
