[Samba] Samba update to 4.10 (on Centos 7.8) - broken -?

[lejeczek]

hi guys

I've just let the system to get big update to 7.8 and with
it came new Samba(4.10.4-10.el7.x86_64), a version with now
fails on my boxes for no apparent reasons.
My Samba uses LDAP backend but I can see no errors related
to that neither.
