This seems relevant for example: ``` #ifdef HAVE_GSS_KRB5_CRED_NO_CI_FLAGS_X /* The krb5 mechanism automatically adds INTEG and CONF flags even when * not specified, this has the effect of rendering explicit requests * of no confidentiality and integrity via setting maxssf 0 moot. * However to interoperate with Windows machines it needs to be * possible to unset these flags as Windows machines refuse to allow * two layers (say TLS and GSSAPI) to both provide these services. * So if we do not suppress these flags a SASL/GSS-SPNEGO negotiation * over, say, LDAPS will fail against Windows Servers */ ``` We should probably do the same in kerberos.dll.
