****************************************************************
If the contextPool is disabled in LDAP configuration of VMM,
a login call fails with VMM. It typically happens if
the ldapServerType is custom. While acquiring a lock for a
semaphore the check was missing to see if the if Context pool
is not enabled.

Problem conclusion

This fix checks the status of the context pool before
acquiring the lock for the semaphore.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.35, 8.0.0.10 and 8.5.5.4  Please refer to the
