Update Samba4* supplimentary libraries to the newer versions.
Made databases/ldb to depend on openldap-sasl-client, so it won't conflict with
the corresponding requirement of net/samba4* ports.
Update of the port to 1.1.15 release.
Change maintaner to myself according to IRC conversation and following e-mail.
[21:50] [aweits(~aweits@discipline.rit.edu )] yea, please take ownership
