thanks.

"can't contact ldap server" can mean bunch of things, if ldap server reachable , you're using simple bind on ssl here, means apache doesn't trust certificate ldap server presenting.

you need tell apache certificate can create ssl connection.

this section of apache docs need: http://httpd.apache.org/docs/2.2/mod/mod_ldap.html#usingssltls

the best way obtain ca certificate ca signed certificate on ldap servers, , use ldaptrustedglobalcert directive. example, 1 of boxes:

ldaptrustedglobalcert cert_base64 /etc/openldap/cacerts/cacert.pem

how go obtaining ca cert varies; ldap servers running certs signed our own ca, can ca cert. setup may different; consult whoever looks after ldap server.

you can obtain certificate ldap server presents using openssl tools:

openssl s_client -connect your.ldap.host:636 2>&1 | sed -ne '/-begin certificate-/,/-end certificate-/p'

that'll display certificate. copy (including begin certificate , end certificate) file.

now add directive:

ldaptrustedglobalcert cert_base64 /path/to/your/cert/file

to top of apache configuration. restart apache, , you're done.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
