What can I do when I can't log in to the Barracuda Spam Firewall using LDAP Single-Sign On (SSO)?

Solution #00005607

Scope:
This solution applies to the Barracuda Spam Firewall, firmware version 4.0 and higher.

Answer:
If you find that you can not log in to your Barracuda Spam Firewall using Single-Sign On (SSO), it could be because of one of the following reasons:

1. Misconfigured SSL/TLS Mode in LDAP Configuration
It could be that your LDAP bind was not successful because the SSL/TLS Mode setting in the LDAP Configuration setting is not correct. You can correct this by navigating to:

Domains > Domain Manager > Manage Domain (Your Domain) > Users > LDAP Configuration

Ensure that the SSL/TLS Mode setting (either 'StartTLS' or 'LDAPS') matches your servers configuration. If you're not sure which to use, try one and save your changes, and then re-run the LDAP bind using the 'Test LDAP' button at the bottom of the screen to ensure a successful bind.

2. Entries in LDAP with duplicate attributes
It could be that your LDAP bind was not successful because of a duplicate attribute, like "mail=", in your LDAP directory. For example, you may have an entry for 'Joe' with an attribute of 'mail=joe@domain.com' and a mailing list that ALSO has an attribute of 'mail=joe@domain.com'. This will cause your bind lookup to return more than one result, and the bind will fail. Changing one of the conflicting attributes to be unique should solve this problem.

After changing the value, you can re-run the LDAP bind using the 'Test LDAP' button at the bottom of the screen to ensure a successful bind.


If neither of these solutions resolve your LDAP binding problem, please contact Barracuda Technical Support and a technician can assist you.
