#1447 Fail over does not work correctly when IPA server is establishing a GSSAPI-encrypted LDAP connection
Closed: Fixed None Opened 6 years ago by jhrozek.

In the failover, we treat both KDC and LDAP on the IPA server as a single "port", numbered 0. This was done in order to make sure that the SSSD always talks to the same server for both LDAP and Kerberos.

However, this clever hack breaks when the IPA provider needs to establish an GSSAPI encrypted LDAP connection because we're asking the fail over code to yield a server while no server has yet been marked as tried. This triggers a fail over for the KDC, so in effect, the TGT is received from second server.

If the second server is not available for some reason, the whole provider goes offline.

The fail over needs to detect that the server asked for is still being resolved and return the same pointer.
