gem uninstall problem
133183 [jim@fr ez .o] Gems is giving me fits with uninstalling activerecord,
133184 [jim@we ri hh] The current gems software is a bit sloppy in its dependency evaluations

ruby-ldap rebinding ?
133265 [rasputnik@he] Can anyone tell me where I'm going wrong here?

133366 [rasputnik@he] Ok thanks - I've used Perl::LDAP in the past which lets you rebind and
133411 [ian@ca ib n.] Yes, I'm afraid you need a new connection to bind as a different user.
133414 [rasputnik@he] Yeah, but then I need to code an admin user/pass pair into my script,
133422 [ian@ca ib n.] You could consider using SASL and something like GSSAPI instead, but
133433 [ian@ca ib n.] This feature is now in Ruby/LDAP's CVS and will be released in 0.9.1.
133435 [rasputnik@he] Brilliant, thanks Ian!
133470 [ian@ca ib n.] You're welcome.
133472 [ian@ca ib n.] And I spoke too soon, because SSLConn connections are more complicated.
133558 [ian@ca ib n.] This has now been fixed in CVS. SSL connections can now also be rebound.
133594 [rasputnik@he] Lovely, ta. Out of interest, is there a reason you need to unbind before binding?
133784 [ian@ca ib n.] It all depends on how much transparency you want.
133794 [rasputnik@he] I think that's what feels wrong about a bind just clobbering the existing
