Hi,

I’m using my IPA server in docker. I’m using that server last more than 8-9 months for ssh login.

Everything works well till few hours before.

I can’t login to ssh and I get this strange error:

[sssd[ldap_child[2171]]][2171]: Failed to initialize credentials using keytab [MEMORY:/etc/krb5.keytab]: Preauthentication failed. Unable to create GSSAPI-encrypted LDAP connection.

Thank you.
