Description:

Hello,

I need to connect to Postgres through a JDBC connection in Kerberos mode.
This is successful only using the JAAS configuration file. Is there way
without using the JAAS conf file I can set
this property in the program that are listed in JAAS conf file.
My required is not to profile the static JAAS file instead I need to send
the properties.
The tickecache and just the login module?
Properties properties = new Properties();
properties.setProperty("cache",
"C:\\temp\\postgresk\\krb5cache");
properties.setProperty("loginmodule",
"com.sun.security.auth.module.Krb5LoginModule");
pgjdbc {
com.sun.security.auth.module.Krb5LoginModule required
debug=true
refreshKrb5Config=true
doNotPrompt=true
useTicketCache=true
useKeyTab=false
client=true
ticketCache="C:\\temp\\postgresk\\krb5cache";
};

As far as I know that is the only way to use JAAS on windows.
