CSCth51156 - Extracting Custom Web Authentication Tar Package May Fail on 5500 WLC

Well I came across a bug that really threw me, basically all those years making tar files and now I had to find a Unix tool to do it. I didn’t use gnuwin32 as it was a nightmare to find and install but Cygwin was awesome, loaded staright away and had my head around it in about 30 minutes.

Also you need to purchase PowerArchiver which I always hate buying software when there are free options available.

Symptom:
When running 7.0.98.0 WLC code on a 5508 WLC, the tar extraction process may fail generating the following error:

Error extracting webauth files.

Conditions:
This condition only occurs on a 5508 running the 7.0.98.0 code. The same
package can be loaded on a 4404 running 7.0.98.0 successfully, and also to a 5508 running 6.0.196.0.

Workaround:
Create .tar package using the following command on UNIX or Windows (via
http://gnuwin32.sourceforge.net/packages/gtar.htm):
tar -cvf login.tar < file1> < file2> < file#>...
