NAME
GSSAPI::OID - methods for handling GSSAPI OIDs and some constant OIDs SYNOPSIS
use GSSAPI; #$oid = GSSAPI::OID->new; # rarely needed or wanted $status = GSSAPI::OID->from_str($oid, "{ 1 2 840 113554 1 2 1 1 }"); # # only supported on MIT Kerberos # $status = $oid->to_str($str); # # only supported on MIT Kerberos # $status = $oid->inquire_names($oidset); # Constant OIDs provided: $oid = gss_nt_user_name; $oid = gss_nt_machine_uid_name; $oid = gss_nt_string_uid_name; $oid = gss_nt_service_name; $oid = gss_nt_exported_name; $oid = gss_nt_service_name_v2; $oid = gss_nt_krb5_name; $oid = gss_nt_krb5_principal; $oid = gss_mech_krb5; $oid = gss_mech_krb5_old; $oid = gss_mech_krb5_v2; $oid = gss_mech_spnego; # if your GSSAPI implementation supports # SPNEGO (Heimdal 0.7 for example # you can use mechtype OID::gss_mech_spnego. # # use GSSAPI::indicate_mechs( $oidset ); # to get the of mechtypes your implementation supports $oid = gss_nt_hostbased_service; # GSS_C_NT_HOSTBASED_SERVICE DESCRIPTION
"GSSAPI::OID" objects are used as unique indentifiers/constants for 'mechanisisms' -- the particular protocol and version being used -- and for the encodings used to represent names. In many cases you can request the default mechanism or encoding for the implmentation by using GSS_C_NO_OID. Check the description of the routine in rfc2743 if you're not sure. AUTHOR

NAME
GSSAPI - Perl extension providing access to the GSSAPIv2 library SYNOPSIS
use GSSAPI; my $targethostname = 'HTTP@moerbsen.grolmsnet.lan'; my $status; TRY: { my ($target, $tname, $ttl ); $status = GSSAPI::Name->import( $target, $server, GSSAPI::OID::gss_nt_hostbased_service) or last; $status = $target->display($tname) or last; print " using Name $tname"; my $ctx = GSSAPI::Context->new(); my $imech = GSSAPI::OID::gss_mech_krb5; my $iflags = 0 ; my $bindings = GSS_C_NO_CHANNEL_BINDINGS; my $creds = GSS_C_NO_CREDENTIAL; my $itime = 0; my $itoken = q{}; my $otoken; $status = $ctx->init($creds,$target, $imech,$iflags,$itime,$bindings,$itoken, undef, $otoken,undef,undef) or last; $status = $ctx->valid_time_left($ttl) or last; print " Security context's time to live $ttl secs"; } unless ($status->major == GSS_S_COMPLETE ) { print " Errors: ", $status; } else { print " seems everything is fine, type klist to see the ticket "; DESCRIPTION
This module gives access to the routines of the GSSAPI library, as described in rfc2743 and rfc2744 and implemented by the Kerberos-1.2 distribution from MIT. Since 0.14 it also compiles and works with Heimdal. Lacks of Heimdal support are gss_release_oid(), gss_str_to_oid() and fail of some tests. Have a look at the tests in t/ directory too see what tests fail on Heimdal ( the *.t tests are just skipping them at the moment) The API presented by this module is a mildly object oriented reinterpretation of the C API, where opaque C structures are Perl objects, but the style of function call has been left mostly untouched. As a result, most routines modify one or more of the parameters passed to them, reflecting the C call-by-reference (or call-by-value-return) semantics. All users of this module are therefore strongly advised to localize all usage of these routines to minimize pain if and when the API changes. USAGE
This module wraps the GSSAPI C-Bindings. If you are new to GSSAPI it is a good idea to read RFC2743 and RFC2744, the documentation requires you to be familiar with the concept and the wordings of GSSAPI programming. the examples directory holds some working examples of usage: getcred_hostbased.pl gets a GSSAPI Token for a service specified on commandline. (like kgetcred on Heimdal or kvno on MIT) gss-client.pl a simple GSSAPI TCP client. gss-server.pl a simple GSSAPI TCP server. Use both as templates if you need quickhacking GSSAPI enabeled GSSAPI TCP services. GSSAPI::Name GSSAPI internal representation of principalname Methods import( $gssapinameobj, $servicename, $mechnism_oid ); converts stringrepresentation $servicename of service into a GSSAPI internal format and stores it in $gssapiservicename. input servicename Scalar value, like 'HTTP@moerbsen.grolmsnet.lan'. mechnism_oid Chose one of the predefines mechanism OIDs from GSSAPI::OID output $gssapinameobj GSSAPI internal representation of servicename return value returns GSSAPI::Status Object Example: $status = GSSAPI::Name->import( $gssapinameobj, 'HTTP@moerbsen.grolmsnet.lan', GSSAPI::OID::gss_nt_hostbased_service); display($tname); converts the GSSAPI internal format into a humanreadable string and stores it into $tname. output humanreadable string will be stored into $tname. return value returns GSSAPI::Status Object Example: my $tname; $status = $gssapinameobj->display($tname); die 'hmm, error...' if($status->major != GSS_S_COMPLETE ); print " Name is $tname"; compare( nameobj, ret) Wraps gss_compare_name(). Input nameobj the 2nd GSSAPI::Name to be compared to output ret value is non-zero names refer to same entity value is zero names refer to different entities. return value returns GSSAPI::Status Object EXPORT GSS_C_ACCEPT GSS_C_AF_APPLETALK GSS_C_AF_BSC GSS_C_AF_CCITT GSS_C_AF_CHAOS GSS_C_AF_DATAKIT GSS_C_AF_DECnet GSS_C_AF_DLI GSS_C_AF_DSS GSS_C_AF_ECMA GSS_C_AF_HYLINK GSS_C_AF_IMPLINK GSS_C_AF_INET GSS_C_AF_LAT GSS_C_AF_LOCAL GSS_C_AF_NBS GSS_C_AF_NS GSS_C_AF_NULLADDR GSS_C_AF_OSI GSS_C_AF_PUP GSS_C_AF_SNA GSS_C_AF_UNSPEC GSS_C_AF_X25 GSS_C_ANON_FLAG GSS_C_BOTH GSS_C_CALLING_ERROR_MASK GSS_C_CALLING_ERROR_OFFSET GSS_C_CONF_FLAG GSS_C_DELEG_FLAG GSS_C_EMPTY_BUFFER GSS_C_GSS_CODE GSS_C_INDEFINITE GSS_C_INITIATE GSS_C_INTEG_FLAG GSS_C_MECH_CODE GSS_C_MUTUAL_FLAG GSS_C_NO_BUFFER GSS_C_NO_CHANNEL_BINDINGS GSS_C_NO_CONTEXT GSS_C_NO_CREDENTIAL GSS_C_NO_NAME GSS_C_NO_OID GSS_C_NO_OID_SET GSS_C_PROT_READY_FLAG GSS_C_QOP_DEFAULT GSS_C_REPLAY_FLAG GSS_C_ROUTINE_ERROR_MASK GSS_C_ROUTINE_ERROR_OFFSET GSS_C_SEQUENCE_FLAG GSS_C_SUPPLEMENTARY_MASK GSS_C_SUPPLEMENTARY_OFFSET GSS_C_TRANS_FLAG GSS_S_BAD_BINDINGS GSS_S_BAD_MECH GSS_S_BAD_NAME GSS_S_BAD_NAMETYPE GSS_S_BAD_QOP GSS_S_BAD_SIG GSS_S_BAD_STATUS GSS_S_CALL_BAD_STRUCTURE GSS_S_CALL_INACCESSIBLE_READ GSS_S_CALL_INACCESSIBLE_WRITE GSS_S_COMPLETE GSS_S_CONTEXT_EXPIRED GSS_S_CONTINUE_NEEDED GSS_S_CREDENTIALS_EXPIRED GSS_S_CRED_UNAVAIL GSS_S_DEFECTIVE_CREDENTIAL GSS_S_DEFECTIVE_TOKEN GSS_S_DUPLICATE_ELEMENT GSS_S_DUPLICATE_TOKEN GSS_S_FAILURE GSS_S_GAP_TOKEN GSS_S_NAME_NOT_MN GSS_S_NO_CONTEXT GSS_S_NO_CRED GSS_S_OLD_TOKEN GSS_S_UNAUTHORIZED GSS_S_UNAVAILABLE GSS_S_UNSEQ_TOKEN Exportable functions $status = indicate_mechs($oidset) Example use GSSAPI qw(:all); my $oidset; my $isin = 0; my $status = indicate_mechs( $oidset ); $status->major == GSS_S_COMPLETE || die 'error'; $status = $oidset->contains( gss_mech_krb5_old, $isin ); $status->major == GSS_S_COMPLETE || die 'error'; if ( $isin ) { print 'Support of Kerberos 5 old mechtype'; } else { print 'No Support of Kerberos 5 old mechtype'; } Constant OIDs provided: # Constant OIDs provided: $oid = gss_nt_user_name; $oid = gss_nt_machine_uid_name; $oid = gss_nt_string_uid_name; $oid = gss_nt_service_name; $oid = gss_nt_exported_name; $oid = gss_nt_service_name_v2; $oid = gss_nt_krb5_name; $oid = gss_nt_krb5_principal; $oid = gss_mech_krb5; $oid = gss_mech_krb5_old; $oid = gss_mech_spnego; All other functions are class or instance methods.
