Thanks for reporting the issue and providing a patch Alexey.

Could you provide the patch as file attachment with the "grant license to ASF", so that we can apply your patch with no licensing issue?

>             Project: Ivy
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0.0-beta-1
>         Environment: Developer: Windows XP, jdk1.6.0_02, ant-1.7.0, jsch-0.1.36
> SFTP Server: FreeBSD-6.2-RELEASE.

> PROBLEM:
> We defined two resolvers in a settings file:
> 	<resolvers>
> 		<sftp name="remote1">
> 			<ivy pattern="sftp://user:password@host:12345/repository/[module]/[module]-[revision].xml"/>
> 			<artifact pattern="sftp://user:password@host:12345/repository/[module]/[artifact]-[revision].[ext]"/>
> 		</sftp>
> 		<sftp name="remote2" host="host" port="12345" user="user" userPassword="password">
> 			<ivy pattern="repository/[module]/[module]-[revision].xml"/>
> 			<artifact pattern="repository/[module]/[artifact]-[revision].[ext]"/>
> 		</sftp>
> 	</resolvers>
> Then we tried to publish our artifacts 
> <ivy:publish resolver="remote1" pubrevision="1.2.3.4" overwrite="true" artifactspattern="${basedir}/files/[artifact].[ext]" />
> or 
> <ivy:publish resolver="remote2" pubrevision="1.2.3.4" overwrite="true" artifactspattern="${basedir}/files/[artifact].[ext]" />
> As a result we had received java.io.IOException with message "Auth fail".
> SOLUTION:
> Our solution is to implement interface com.jcraft.jsch.UIKeyboardInteractive in class CfUserInfo in file SshCache.java. Patch had been attached below.
