Impossible to connect to SSH or to SMTP

You mean, to reset ldap-accounts.cf and ldap-aliases.cf?

Well, it is late now, i thank you for your help, you are precious to me.
i will continue searching tomorrow

I have already resetted ldap-counts.cf and ldap-aliases.cf some days ago, but it doesn’t change anything.
This is a work-around to create aliases for my family without creating accounts.
These two files should not change LDAP results for SSH, i used this workaround for years.
Everything is described here

Nevertheless, i will make sure tomorrow and reset these files

Good night
