phantom locking issues - 403 Forbidden

[William Muriithi]

Hello,

I have a locking issue that show up as follows:

On the SVN client:
Error: Unlock for FileABC.OLB failed (403 Forbidden)
Error: If you want to break the lock, use the "Check For Modification"
dialog or the repository browser


On the SVN server:
[Tue Mar 07 16:32:35 2017] [error] [client 192.168.11.1] Access
denied: 'waqar' LOCK
projects:/applications/trunk/work/Library/Allegro/FileABC.OLB

When I used the command below, it failed with the message file now locked.

svn unlock --force
https://carbon.eng.example.com/svn/projects/applications/trunk/work/Library/Allegro/FileABC.OLB

I then ssh to the SVN server and attempted to search for the lock.

svnadmin lslocks /var/svn/projects | grep -B 6 FileABC.OLB

This came back with no match. At this point, I got lost. What would
I be missing? A bit of background, the issue started because for a
day, I had started to use kerberos for authentication that introduced
a different user for every uid. Rolling back the change hasn't helped

Any pointer on how to investigate further?

Regards,
William
