Hi @baumber13,
Apologies for my late response.

If I had to guess, I'd say it's the $${user} part of the config that's causing issues. Is the double $ purposeful? I know that's sometimes used in docker-compose configs, as an escape to mean a single literal dollar.

[baumber13]

Hi,

Yeah you are correct, I did that for when I was trying to do wit via docker-compose however I am now trying to get it to work via the .env file. I have now removed the double $ but still getting the same error.

Thanks

Looking again at where this is erroring, I'd imagine it could only imagine it's something in the LDAP_SERVER value.

Any special characters in there?
Are you defining the protocol in the string? If so, which one?

[baumber13]

There was hyphens but I did try with just IP and no luck. I used ldapsearch and connected successfully over 389 so used a value like;

192.168.1.1:389
VM-SRV-DC:389

Thanks

Issue was resolved via removing and reinstalling php ldap as I tested on another fresh install and worked first time.

Thanks for the help!!
