Hi All. I have a problem with authorization users AD via kerberos in Dovecot&Postfix. Windows SRV 2008 Standart - AD mail server: Gentoo + cyrus-sasl + postfix + dovecot with support ldap&kerberos. I am created a 4 keytabs on Windows box.
C:\Users\Admin>ktpass -princ host/srv-mail.cn.energy@CN.ENERGY -mapuser ldapmail@CN.ENERGY -pass "superpasswd" -crypto RC4-HMAC-NT -ptype KRB5_NT_PRINCIPAL -out c:\mail.keytab
etc... for all
imap/srv-mail.cn.energy pop/srv-mail.cn.energy smtp/srv-mail.cn.energy host/srv-mail.cn.energy
On Linux server: ktutils ktutils: rkt /root/Keytab/imap.keytab ktutils: rkt /root/Keytab/smtp.keytab ktutils: rkt /root/Keytab/pop.keytab ktutils: rkt /root/Keytab/host.keytab ktutils: wrt /etc/krb5.keytab ktutils: q
kinit -V -k -t /etc/krb5.keytab host/srv-mail.cn.energy@CN.ENERGY Authenticated to Kerberos v5
KRB5_KTNAME=/etc/krb5.keytab ; export KRB5_KTNAME
TESTING: imtest srv-mail ERROR: Mar 10 08:27:23 srv-mail dovecot: auth(default): auth(?,10.0.0.5): Invalid username: host/srv-mail.cn.energy@CN.ENERGY Mar 10 08:27:23 srv-mail dovecot: auth(default): gssapi(?,10.0.0.5): authn_name: Username contains disallowed character: 0x2f Why username "host/srv-mail.cn.energy@CN.ENERGY" ???
