Help converting SunOS /etc/security/passwd.adjunct format to Linux /etc/shdow format

I am in the process of trying to retire my last SunOS 4.1.4 box. It has been the NIS master for years because Linux can understand it's triple-DES (not very secure) password encryption but SunOS 4.1.4 can not understand the more advanced encryption provided by Linux.

So I am faced with trying to convert the old passwd.adjunct format into
linux format, if I just put the entries in as is, pwck bitches about it being an invalid line, wants to delete, then bitches no line exists and adds a new line in with no password. This obviously is no good. I know that Linux knows how to use a triple DES entry because it did so fine as a NIS slave with a SunOS NIS master.

Any suggestions?

Never mind, problem solved. For anyone else ever running into this issue, converting from SunOS to Linux, edit /etc/passwd.yp and change all the entires that have user:##user:, to user:x:. Edit out all the system entries at the beginning of the file. Then exit /etc/security/passwd.adjunct.yp. Remove the same system entries and add two :: at the end of each line so the number of fields is what Linux expects. Now cat /etc/passwd.yp >> /etc/passwd on the linux box, cat /etc/security/passwd.adjunct.yp >> /etc/shadow, run pwck -s and then pwck -r to see any errors, such as missing directories, fix all errors, then make your machine a NIS master with ypinit -m. That's all folks!

Well now a new mystery, new NIS master and slaves all setup, and finally resolved the issue with ypxfrd, firewall was blocking the port. Now yppasswd wants to use the old NIS master even though it's gone from the configs of all the machines, don't
know if something is hanging onto it in memory or what.
