1.5.x obtains locks from the file servers whereas 1.4.x did not.

The 'l' permission controls read locks not write locks.   Write locks
are controlled by the 'w' permission or the 'i' permission of the client
owns the file.

The behavior is not intended.  If it is the case, please file a bug
report to openafs-bugs@openafs.org.
