Problem with authentication against FreeIPA

[Daniel Osielczak]

Thanks Alan,

the error is a bit misleading I guess.

[13:53:39] root at freeradius:~ # rpm -q --whatprovides /usr/lib64/freeradius/rlm_ldap.so
freeradius-ldap-3.0.19-2.el7.x86_64

Given that the package comes from the NetworkRadius repo, I don't think there is a easy way around it (other than building the library with SASL enabled, which adds quite a burden to maintenance).

Thanks for all the help,
Daniel

  The message really means that SASL was not found when rlm_ldap was built.  It doesn't really matter if libldap provides a ldap_sasl_interactive_bind function, as it's hard for rlm_ldap to determine that at run-time.

  rlm_ldap has to be built with SASL support.  See the output of configure as to why it's not building with SASL support.
