Title: #5264: Utils: White space replace with another character
I think this is not a correct solution since having the override character in name is in
fact a real problem in the environment. It will either make the user unresolvable or even
worse it will return different user if you have both names "user_1" and
"user 1" in LDAP.
I think the root cause is that this option is set globally for the whole SSSD and ssh_keys
is a local user. If it is a local user then we should probably figure out if we can
somehow avoid using this override for files provider. If it is an LDAP user then they need
to fix it on their side.
