 From the command line you user can use

   kinit -4 <user@YOUR.REALM>
   aklog -4 <your.cell>

However, you should probably start to consider a transition to a 
Kerberos 5 KDC and OpenAFS 1.2.x in the near future.  Kerberos 4 support 
is being removed from MIT Kerberos within two years and the OpenAFS 2.0
release is going to depend quite heavily on GSS-API and Kerberos 5
crypto for securing your data.
