Kerberos- GSS-API C code issues

[Tadoori (EXT), Vilas]

Hi,
I have written an GSSAPI server application and the kerberos is MIT V5.
When I run my application on the sun solaris  I get the following
message
I have checked that the kerberos is running or not, and I see that
kerberos is running fine.
This code is written in C
 
Please find the below message after running the GSS API testserver.

I would greatly appreciate if anyone can help me solve this issue.
