.Dd May 10, 2005 .Dt KRB5_COMPARE_CREDS 3 .Os HEIMDAL .Sh NAME .Nm krb5_compare_creds .Nd compare Kerberos 5 credentials .Sh LIBRARY Kerberos 5 Library (libkrb5, -lkrb5) .Sh SYNOPSIS n krb5.h .Ft krb5_boolean .Fo krb5_compare_creds .Fa "krb5_context context" .Fa "krb5_flags whichfields" .Fa "const krb5_creds *mcreds" .Fa "const krb5_creds *creds" .Fc .Sh DESCRIPTION .Fn krb5_compare_creds compares .Fa mcreds (usually filled in by the application) to .Fa creds (most often from a credentials cache) and return .Dv TRUE if they are equal. Unless .Va mcreds-\*[Gt]server is .Dv NULL , the service of the credentials are always compared. If the client name in .Fa mcreds is present, the client names are also compared. This function is normally only called indirectly via .Xr krb5_cc_retrieve_cred 3 .
p The following flags, set in .Fa whichfields , affects the comparison: l -tag -width KRB5_TC_MATCH_SRV_NAMEONLY -compact -offset indent t KRB5_TC_MATCH_SRV_NAMEONLY Consider all realms equal when comparing the service principal. t KRB5_TC_MATCH_KEYTYPE Compare enctypes. t KRB5_TC_MATCH_FLAGS_EXACT Make sure that the ticket flags are identical. t KRB5_TC_MATCH_FLAGS Make sure that all ticket flags set in .Fa mcreds are also present in .Fa creds . t KRB5_TC_MATCH_TIMES_EXACT Compares the ticket times exactly. t KRB5_TC_MATCH_TIMES Compares only the expiration times of the creds. t KRB5_TC_MATCH_AUTHDATA Compares the authdata fields. t KRB5_TC_MATCH_2ND_TKT Compares the second tickets (used by user-to-user authentication). t KRB5_TC_MATCH_IS_SKEY Compares the existance of the second ticket. .El .Sh SEE ALSO .Xr krb5 3 , .Xr krb5_cc_retrieve_cred 3 , .Xr krb5_creds 3 , .Xr krb5_get_init_creds 3 , .Xr kerberos 8
