Comment 2 for bug 1773747

I installed a new system with 20.04 and sssd-common.
Unfortunately the alternative for idmap-plugin from sssd is still not available by update-alternatives:

# update-alternatives --config idmap-plugin
There is only one alternative in link group idmap-plugin (providing /etc/cifs-utils/idmap-plugin): /usr/lib/x86_64-linux-gnu/cifs-utils/idmapwb.so
Nothing to configure.

I had to sym-link it manually:

rm /etc/alternatives/idmap-plugin
ln -s /usr/lib/x86_64-linux-gnu/cifs-utils/cifs_idmap_sss.so /etc/alternatives/idmap-plugin
