Overview of Building a Kerberos Application
on OpenVMS
Kerberos programming on OpenVMS works much the same as on
any other platform. The following sections indicate differences
and important information.
Compiling a Kerberos
Program on OpenVMS When you compile your program, you will need to add the /INCLUDE=KRB$ROOT:[INCLUDE] qualifier
to your compiler command line. For example:
Linking a Kerberos Program on OpenVMS Kerberos on OpenVMS provides shareable libraries in both 64-bit
and 32-bit formats. All Kerberos libraries can be found in SYS$LIBRARY.
Library Name
Bit Format
GSS$RTL.EXE
64 bits
GSS$RTL32.EXE
32 bits
KRB$RTL.EXE
64 bits
KRB$RTL32.EXE
32 bits
One of the GSS$RTL* libraries should
be used when your program calls the GSS API. If the KRB5 API is called,
then one of the KRB$RTL* libraries will
need to be linked with the program.
Because Kerberos routines are located in shareable libraries,
the use of a link options file is recommended. For details about
using link options files, refer to the HP OpenVMS Linker
Utility Manual. The Kerberos example programs described
in this chapter provide examples of using link options files for
Kerberos applications.
