Credentials cache I/O operation failed XXX

[Jonathan Maybaum <maybaum@xxxxxxxxx>]

Cosign discuss,
Has anyone seen this error? It occurs after a login that seems  
successful, in that the krb5kdc log shows that a ticket was issued.

The title of the error page is "CC Initialize error" and I see the  
following in login.c but don't know what the error means:

    if (( kerror = krb5_cc_initialize( kcontext, kccache, kprinc )) ! 
= 0 ) {
    sl[ SL_ERROR ].sl_data = (char *)error_message( kerror );
    sl[ SL_TITLE ].sl_data = "CC Initialize Error";
    tmpl = ERROR_HTML;
    subfile( tmpl, sl, 0 );
    exit( 0 );
    }

OS X Server 10.4.2, cosign 1.8.5 (at least, that's what the download  
said, although cosignd -V returns 1.8.0)
