Dotaz: pGina - TLS error

[Deryl]

Ahoj,

snažím se autentizovat uživatele Win 7 vůči openLDAP (CentOS, docker - osixia/openldap:1.3.0 ) a na serveru vidím v logu:

2019-12-03T21:07:33.050978000Z 5de6ce95 conn=8216 op=0 STARTTLS
2019-12-03T21:07:33.051101000Z 5de6ce95 conn=8216 op=0 RESULT oid= err=0 text=
2019-12-03T21:07:33.053499000Z TLS: can't accept: A packet with illegal or unsupported version was received..
2019-12-03T21:07:33.053816000Z 5de6ce95 conn=8216 fd=12 closed (TLS negotiation failure)

Linuxový klient bez problémů.

pGina ani pGina.fork nehýří aktualizacemi - je možné, že podporuje příliš staré TLS/SSL, které je již v aktuálních distribucích zakázané?

openLDAP výchozí nastavení:

LDAP_TLS_CIPHER_SUITE = SECURE256:+SECURE128:-VERS-TLS-ALL:+VERS-TLS1.2:-RSAHE-DSS:-CAMELLIA-128-CBC:-CAMELLIA-256-CBC

Je případně jiná možnost ověřování uživatelů Win 7 vůči openLDAP? (Než pGina.)

Odpovědi

[NN]

Je to naopak. Ve Win 7 nevyhovujici TLS 1.0. Opravit to muzes snizenim bezpecnosti na strane serveru, nebo lepe povolenim bezpecnejsiho TLS1.1/1.2 na strane klienta.

[Deryl]

Díky.

Povolení TLS 1.2 ve Win registrech u klienta problém vyřešilo.
