- All Implemented Interfaces:
- javax.security.auth.callback.CallbackHandler
public class WSCcacheCallBackHandlerImpl extends java.lang.Object implements javax.security.auth.callback.CallbackHandler
The
WSCcacheCallBackHandlerImpl
gathers the authentication data from the contructor and push them throughs to the login module. These data includes Kerberos principal name, Kerberos realm name, Kerberos credential cache file name and use the default Kerberos credential cache.Supported

. The text to be used as the Kerberos credential cache fully qualified file name.javax.security.auth.callback.TextInputCallback
. The text to be used as the use default Kerberos credential cache.
NOTE: In order to use the Kerberos credential cache, You must set all options to false in the WSKRB5Login module entry in the wsjaas_client.conf file.

WSCcacheCallBackHandlerImpl
public WSCcacheCallBackHandlerImpl(java.lang.String userid, java.lang.String realmName, java.lang.String ccacheFile, java.lang.String defaultCcache)
Constructs aWSCcacheCallBackHandlerImpl
usinguserid
,realmName
,ccacheFile
anddefaultCcache
parameters.- Parameters:
userid
- The Kerberos user name.realmName
- The Kerberos realm name.ccacheFile
- The Kerberos credential cache file name. The value is an URL, FILE:<user specific directory and file name>. For example: 'FILE:/utle/krb5cc_utle'. If you want to use the default Kerberos credential cache, then this parameter can be null.defaultCcache
- The default Kerberos credential cache. It's a string value of either 'true' or 'false'. If defaultCcache is 'true', the default Kerberos credential cache will be used. The default cache is located in the following order:- <user.home>/krb5cc_<user.name>, where <user.home> and <user.name > are the Java user.home and user.name properties respectively.
- <user.home>/krb5cc (if <user.name> cannot be obtained from the JVM).
NOTE: If defaultCcache is 'true' while the default Kerberos credential cache is invalid/missing/expired, or userid=null, the WSKrb5Login will attempt to use Microsoft native credentials if the running platform is Windows.
