nas - Why won't synology CVS allow user login? -

i'm trying set cvs server on synology nas, getting recurring error in accessing cvs via login. i'm posting on synology server, thought i'd post here it's more of cvs issue synology issue.

i followed these instructions set cvs http://forum.synology.com/wiki/index.php/step-by-step_guide_to_installing_cvs_server

here's result of login:

$ cvs -d :pserver:user1@redacted.org:/opt/cvsroot login

cvs login: authorization failed: server redacted.org rejected access /opt/cvsroot user user1

results of various checks:

$ netstat -l | grep cvs

tcp 0 0 0.0.0.0:cvspserver 0.0.0.0:* listen

..

$ cat /etc/services | grep cvs

cvspserver 2401/tcp # cvs client/server operations

cvspserver 2401/udp # cvs client/server operations

cvsup 5999/tcp cvsup # cvsup file transfer/john polstra/freebsd

cvsup 5999/udp cvsup # cvsup file transfer/john polstra/freebsd

synology details :: ds2411+ dsm 4.1-2661

the password i'm using correct per /opt/cvsroot/cvsroot/passwd permissions on passwd chmod 400, , owned cvs:cvs.

any thoughts? help.
