Limit of characters for ldap user password?

My apologies if this has been posted or answered somewhere else. I couldn’t find it, even with my fiercest google fu.

We recently made some changes to the user our Openfire server uses to do ldap lookups and we increased the characters in the password. Since doing that, we cannot use that login in Openfire to check ldap. Other accounts with under 10 characters work fine, but that’s not ideal for us - we’d prefer to use the same user we use elsewhere for this purpose. Is there a limit on how many characters can be in the password for that user? If so, does anyone know what that limit is?

I’m referring to the user referenced under Server Settings, LDAP Settings.

Thanks in advance!
