I am new to fedora, whenever i try to use sudo command it shows this error

sudo: error in /etc/sudo.conf, line 0 while loading plugin "sudoers_policy"
sudo: unable to load /usr/libexec/sudo/sudoers.so: libldap.so.2: cannot open shared object file: No such file or directory
sudo: fatal error, unable to load plugins 

I have also tried editing /etc/sudoers.so file in fedora but it didn't work.I'm unable to use root user su - inspite of giving it right password it shows authentication failed.

    For su what do you mean by "the right password"? It should be the starting user's password for sudo but the target user's password for su Jan 20, 2023 at 7:46

Your installation looks broken. Please try this:

su - # assuming you remember your root password
dnf reinstall openldap # if it errors out, just `dnf install openldap`
