After configuring an LDAP User Store and adding the initial connection information, the error "mcc.ui.invalid_cohort" is appearing.
The User Store Name chosen had an invalid invalid character. When creating an LDAP user store, this configures a new tenant internally, therefore invalid characters for tenants also apply to the LDAP user store name.
LDAP User Storage name: MSSN.mss
In this instance, the User Store Name chosen (MSSN.mss) had a full stop/period (.) in it, this is an invalid character.
AXA : 17.3.x
Avoid any special character for use in LDAP user store name/tenants.
