Redmine

Have a new installation of redmine with redmine_ldap_sync plugin installed. Issue is
when signing a user, get this error.

"Invalid user or password". What is being missed here ?

ldap is synced and when testing ( LDAPServers >> LDAPAuth )

for a user it shows

User "a.coatwala":
First name = Abdul Rehman
Last name = Coatwala
Groups = ["AAITEST", "FILM", "SUPP"]

but when signing using this id why does the above error occur.

Knowing it will help trouble shoot it.

Thank you
