Dear community,
I am currently trying to set up a project with sspi authentication on a windows server. I use the jdbc postgresql-42.2.18.jar with a postgres 12.5.
I have downloaded the waffles libraries as recommanded here : https://jdbc.postgresql.org/documentation/94/connect.html and added them to the classpath project.
I have tried this part of code in a Test :
String url = ʺjdbc:postgresql://<serveradress>:<portnumber>/<databasename>?gsslib=sspiʺ;
Connection conn = DriverManager.getConnection(url);
The code throws the following exception :
NoSuchMethodError: com.such.jna.platform.win32.Sspi$SecBufferDesc at org.postgresql.sspi.SSPIClient.continueSSPI(SSPIClient.java :204).
When I looked the pgjdbc github of the SSPIClient class (https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/sspi/SSPIClient.java), I have noticed that the following constructor is used : SecBufferDesc(Sspi.SECBUFFER_TOKEN, receivedToken).
The SecBufferDesc class comes from the jna.platform librairy 5.0.0 (com.sun.jna.platform.win32.Sspi.SecBufferDesc) provided by the waffle librairies 2.3.0.
Looking at the SecBufferDesc class inside the jna.platform 5.0.0, there is only one constructor (SecBufferDesc()). There is no constructor SecBufferDesc(int type, int tokenSize)anymore.
Doing a little research, the problem seems to be known by the waffle community (https://github.com/Waffle/waffle/issues/838).
It seems that it is not possible to use the last Waffle version (2.3.0) to do sspi authentication with the pgjdbc because of that.
Do you know witch version of the Waffle libraries I should use to enable SSPI authentication with the pgjdbc ? Do you think I should report this issue as a bug on the pgjdbc github ?
Thanks for your help,
Regards,
