Public bug reported:
Dear professionals,
When using the regex translation method for idmapping, idmapd complains
about an unresolved symbol (nfsidmap_config_get) in the regex.so shared
object:
systemctl status -l nfs-idmapd.service
● nfs-idmapd.service - NFSv4 ID-name mapping service
Loaded: loaded (/lib/systemd/system/nfs-idmapd.service; static; vendor
preset: enabled)

This symbol obviously does not exist in the libnfsidmap.so.0.3.0 shared object:
readelf -s /usr/lib/x86_64-linux-gnu/libnfsidmap.so.0.3.0 | grep
nfsidmap_config_get
<Nothing>
When checking the sources at https://github.com/isginf/libnfsidmap-
regex/blob/1179b2ec3392c91a40da228afada46fd210113a2/regex.c#L57 it seems
this library is accidentally using the wrong interface since the symbol
"conf_get_str" exists in libnfsidmap.so.0.3.0.
Since the groovy version of the package "libnfsidmap-regex" did not raise the
dependencies, I also checked this one and could verify that it:
a) uses the "conf_get_str" function
b) loads cleanly
I would like to ask you to either re-compile this package correctly or
publish the groovy package version also for focal.
