Hi David,
Not sure I have an answer, but perhaps a few clues.
The error says it cannot determine a user account's full DN:
"failed_login:no DN found for user krbelcher".
So, that implies to me that it *might* be having issues with either
"search_context" or the lack of "object_context". But, nothing jumps
out to me as to why either of those would be problematic.
DSpace definitely will work with Active Directory (I've set it up in the
past), but as each directory structure is a bit different, it's hard to
have standard instructions here.
In the past, I've usually seen AD directory structures which look more like:
dc=relligar,dc=edu
|
|
ou = User Accounts
_/ | \_
_/ | \_
/ | \
ou=Staff Accounts ou=Faculty Accounts ou=Student Accounts
In that scenario, I've set "search_context = ou=User
Accounts,dc=relligar,dc=edu", and found that it worked fine. So, by the
same logic, it *seems* like your "search_context" should be correct, but
there's still obviously something wrong here.
One option may be to try to debug your settings by running similar LDAP
queries using a third-party tool like "ldapsearch" (which is in the
"ldap-utils" Linux Package).
So, for example, using "ldapsearch" you could run test/verification
queries similar to these:
# Returns the first 100 accts (using "subtree" search) under the
search_context (returning just the 'cn', 'mail' and 'sn' fields)
ldapsearch -x -H [provider_url] -D [search.user] -W -b [search_context]
-z 100 -s sub cn mail sn
# Returns the first 100 accts (using "subtree" search) where username
(id_field) starts with "k"
ldapsearch -x -H [provider_url] -D [search.user] -W -b [search_context]
-z 100 -s sub "([id_field]=k*)" [id_field] cn mail sn givenName
If it isn't obvious, all the placeholders above correspond to the values
of configs in authentication-ldap.cfg.
More info on "ldapsearch" commands:
http://www.openldap.org/software/man.cgi?query=ldapsearch&apropos=0&sektion=0&manpath=OpenLDAP+2.0-Release&format=html
Hopefully that gives you some more hints to go on. Please do report
back on your status to this mailing list, as it might help others in the
future (and it could also help us to enhance our documentation around
configuring the LDAP plugin).
