[imp] Problem with alternate login

Make sure your PHP's php.ini configuration is set up correctly for sessions.
I had to play around with the various settings to get mine to work, not
knowing what everything meant.  For example, right now my working HEAD
horde/imp has php.ini settings of:

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
session.save_path = /tmp

; Whether to use cookies.
session.use_cookies =  0


; Name of the session (used as cookie name).
session.name = PHPSESSID
; Initialize session on request startup.
session.auto_start = 0
;session.auto_start = 1

; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0

; The path for which the cookie is valid.
session.cookie_path = /

; The domain for which the cookie is valid.
session.cookie_domain =

; The domain for which the cookie is valid.
session.cookie_domain =

; Handler used to serialize data.  php is the standard serializer of PHP.
session.serialize_handler = php

; Percentual probability that the 'garbage collection' process is started
; on every session initialization.
session.gc_probability = 1

; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
;session.gc_maxlifetime = 1440
session.gc_maxlifetime = 146000

; Check HTTP Referer to invalidate externally stored URLs containing ids.
session.referer_check =

; How many bytes to read from the file.
session.entropy_length = 0

; Specified here to create the session id.
session.entropy_file =
;session.entropy_length = 16

;session.entropy_file = /dev/urandom

; Set to {nocache,private,public} to determine HTTP caching aspects.
session.cache_limiter = nocache

; Document expires after n minutes.
session.cache_expire = 180

; use transient sid support if enabled by compiling with --enable-trans-sid.
session.use_trans_sid = 1

url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry"


Before I got rid of the reason=session problem I was able to prove that
the horde/imp execution was not creating a session in createSession.
