[AG-TECH] grid-proxy-init

[Vandana]

Hi,
   I have re-installed my machine with RedHat 7.3 and trying to use the 
certificate which I had obtained earlier. After I run 
grid-proxy-init I get

> grid-proxy-init
Your identity: /O=Access 
Grid/OU=agdev-ca.mcs.anl.gov/OU=ccs.uky.edu/CN=vandana
Enter GRID pass phrase for this identity:
user key and certificate don't match
Function: proxy_init_cred

What do I need to do. Do I have to get a new certificate? 

Thanks,
Vandana
