To retrieve a policy, use the kadmin get_policy command, which
requires the "inquire" administrative privilege.  The syntax is:
     get_policy [-terse] policy
     
The get_policy command has the alias getpol.  For example:
     kadmin: get_policy admin
     Policy: admin
     Maximum password life: 180 days 00:00:00
     Minimum password life: 00:00:00
     Minimum password length: 6
     Minimum number of password character classes: 2
     Number of old keys kept: 5
     Reference count: 17
     kadmin:
     
The reference count is the number of principals using that policy.
The get_policy command has a -terse option, which lists
each field as a quoted, tab-separated string.  For example:
     kadmin: get_policy -terse admin
     admin   15552000        0       6       2       5       17
     kadmin:
