commit 19723ed0fcdf267ece3dbcde503f86093aceb39b
Author: Andrew Bartlett <abartlet at samba.org>

Partially revert restriction of socket_wrapper to 1500 byte writes
This keeps the restriction for stream sockets (where the caller will
retry), without creating problems on datagram sockets (CLDAP is not
defined, as far as I know, across multiple UDP packets).
The commit adding this restriction was
