Michael,
To follow up on Felix's post.
You can create multiple ldap (ldap entries, one for each ou. cas will search
them the order they are in your properties file.

I changed my config to:
cas.authn.ldap[0].order=0
cas.authn.ldap[0].name=Tech Active Directory
cas.authn.ldap[0].type=AD
cas.authn.ldap[0].ldapUrl=ldap://<hostname>:389
cas.authn.ldap[0].validatePeriod=270
cas.authn.ldap[0].poolPassivator=NONE
cas.authn.ldap[0].searchFilter=sAMAccountName={user}
cas.authn.ldap[0].baseDn=OU=Technology,OU=Staff,DC=CHS,DC=...
cas.authn.ldap[0].dnFormat=CN=%s,OU=Technology,OU=Staff,DC=...
cas.authn.ldap[0].type=AUTHENTICATED
cas.authn.ldap[0].bindDn=CN=casbind,CN=Users,DC=...
cas.authn.ldap[0].bindCredential=<a password>
And now it's working for people in that OU... Time to see if I can expand it to
the entire Staff OU...

Hello all,
Forgive me for this, I'm brand new to CAS and I'm trying to get LDAP working.
I built an Ubuntu VM and did initial setup by doing:
1. git clone https://github.com/apereo/cas-overlay-template
2. I did some initial config changes in the cas.properties to get SSL up and
running
3. Ran sudo ./gradlew clean copyCasConfiguration build run
4. I can login using the casuser and the default password as expected. This
part is all working fine.
So I tried adding LDAP support by:
1. Modify build.gradle by adding
implementation
"org.apereo.cas:cas-server-support-ldap:${project.'cas.version'}"
to the dependencies section.
2. Modify cas.properties by adding:
# Disable casuser
cas.authn.accept.users=
# LDAP Servers Authenticated
cas.authn.ldap[0].ldapUrl=ldap://<ldap server ip>:389
#cas.authn.ldap[0].usessl=false
cas.authn.ldap[0].useStartTls=false
cas.authn.ldap[0].type=AUTHENTICATED
cas.authn.ldap[0].bindDn=cn=cas bind,CN=Users,DC=...
cas.authn.ldap[0].bindCredential=<the password>
# LDAP Servers Authenticated
# Search For CAS User
cas.authn.ldap[0].baseDn=OU=Technology,OU=Staff,DC=CHS,DC=...
cas.authn.ldap[0].subtreeSearch=true
#cas.authn.ldap[0].searchFilter=(&(objectClass=person)(uid={user}))
#cas.authn.ldap[0].searchFilter=uid={user}
cas.authn.ldap[0].searchFilter=sAMAaccountName={user}
#cas.authn.ldap[0].principalAttributeList=cn,givenName,mail,sn
# Search for CAS User
3. Ran sudo ./gradlew clean copyCasConfiguration build run
The page loads as usual. I am unable to login as casuser, which is expected.
I cannot login with any domain credentials.
In the log I get an error:
2022-02-08 15:43:49,567 INFO
[org.apereo.cas.authentication.DefaultAuthenticationManager] -
<[LdapAuthenticationHandler] exception details: [Unable to resolve user dn for
<a username>].>
So I tried to verify that the server can connect via LDAP:
ldapsearch -H ldap://<ldap server ip>:389 -D "CN=cas bind,CN=Users,DC=..." -W
samaccountname=<a username> -b "OU=Technology,OU=Staff,DC=..." -v
And I receive a valid result.
I'm not sure where the disconnect is, or what else I should search for. Any
tips or suggestions that you could provide would be helpful.
I'm attaching the output of Task :run.
