#978 add LDAP provider option to set LDAP_OPT_X_SASL_NOCANON
Closed: Fixed None Opened 12 years ago by jhrozek.

In some cases when SASL is used, openldap might try to canonicalize the hostname by doing a reverse lookup. This might be a blocking call because openldap uses glibc's getnameinfo (The openldap function is ldap_pvt_get_hname).

It is possible to turn off this check by setting LDAP_OPT_X_SASL_NOCANON.

It is not only a problem about blocking on DNS calls.
It may also cause failures to get a ticket because the PTR is wrong. Bad DNs configuration for reverse addresses is very common, especially in test environments, and small networks.
