I have a tree with the same name as the Organization object.
When I try loging in to PKIDIAG then I get a 601 error.
If I create a user in a O with diffenent name than the Treename then login
goes OK.

Treename is COMP
Organization Obj = COMP (Shown in upper case in Console One)
Admin resides in the O=COMP container.
Server Contains replicas of entire tree

Have tried :
admin.COMP.COMP
CN=Admin.O=COMP.T=COMP
cn=Admin.o=COMP.T=COMP
And all above with leading period.

Created a Admin user in O=Test, gave the user S-rights to T=COMP and the
login Admin.Test worked OK

Found once before a TID about correct syntax for logging in when TREENAME
was the same as the O-name, but have not found it now.
