Today, we will explain to you How to fix Unable to Connect to LDAP Server in Joomla's Login site. Here's a fast answer for help Joomla heads or clients who can't login to the administrator range and get the message "Not able to interface with the LDAP Server". LDAP remains for Light Directory Access Protocol. Joomla utilizes a LDAP library to help with confirmation when logging in.

The issue is more than likely because of the secret word being adulterated in the database. The watchword won't work so Joomla can't validate it.
There may times when Joomla's LDAP documents may be adulterated and would need to be supplanted with clean forms, however the techniques portrayed underneath normally alter the issue. We should attempt those first.
You have two choices to attempt to alter this issue.
1. Reset the secret key in the Joomla back-end by altering the client's settings in Joomla's User Manager, or
2. Reset the secret key in your database, specifically.
I needed to utilize the recent strategy not more than a day or two ago on the grounds that I lacked the capacity click the Save & Close symbol in the User Manager in the wake of entering the new watchword.
Resetting the watchword in the database is the same methodology portrayed in a more established article titled "Bolted Out?: Resetting the Joomla Admin Password" with the exception of that as opposed to utilizing the Md5 hash for what used to be the default Joomla secret key, "administrator", you would make a Md5 hash for your fancied secret key and utilize that.
To make the Md5 hash, look on the web for "md5 hash" and pick one of the free online Md5 Hash generators. I utilize Miracle Salad's Md5 Hash Generator.
When you've got your Md5 hash made, select and duplicate it and spare it in a content record.
At that point open up the Users table in your database supervisor device, discover and select the record for the client having the issue, and glue the hash into the Password field. Click the Go catch at the base to spare it, and go test it by attempting to login to Joomla.
Assuredly it worked for you. If not, I'd attempt it a second time to verify you duplicated the hash effectively. On the off chance that it still doesn't work, then reinforcement your site documents and transfer a clean form of the Joomla center records, overwriting the current records the whole time.
