Following a difficult SP1 to SP2 pretty much everything is working apart from iPrint.

I think there's an LDAP configuration problem but I can't find where the settings are set.

When I browse to https://<server>/PSMStatus I'm asked to enter a userid/password and then,
instead of getting the PSMStatus page I get an HTTP 500 error indicating a server problem.

In /var/log/apache2/error_log I get entries like

[Tue Jan 04 13:22:30 2011] [warn] [client <myIP>] [4639] authnz_ldapdn authenticate: user admin authentication failed; URI /PSMStatus [LDAPDN: ldap_simple_bind_s() failed][Can't contact LDAP server], referer: http://<refering URL>

which indicates that there is a problem contacting the ldap server for authentication.

The ldap server is running and other services such as LUM are fine.

So where is the ldap server for apache2 configured?
