I was trying to setup with custom config and kept getting error primary group mismatch so I tried example config and am still getting errors.

Using Docker Hub image v1.1.2 with quickstart example config.

Using example ldapsearch -LLL -H ldap://localhost:3893 -D cn=serviceuser,ou=svcaccts,dc=glauth,dc=com -w mysecret -x -bdc=glauth,dc=com cn=hackers

Returns error ldap_bind: Invalid credentials (49)

And logs Bind WARN 007 Bind Error: User serviceuser primary group is not svcaccts.

Relevant portions of the example config:

[[users]]
  name = "serviceuser"
  mail = "serviceuser@example.com"
  uidnumber = 5003
  primarygroup = 5502
  passsha256 = "652c7dc687d98c9889304ed2e408c74b611e86a40caa51c4b43f1dd5913c5cd0" # mysecret

[[groups]]
  name = "svcaccts"
  gidnumber = 5502
