I can use assistance in adding a projection to the proj.db file.  The custom projection that I would like to add is EPSG 103749 NAD_1983_HARN_Adj_MN_Lyon_Feet which is included with ESRI products.  I also had it working when we had the old nad83 by adding the parameters further below.  Ironically proj 103749 is listed in the crs_view table but I could not find any other reference in the database to 103749.

The two errors that the MapServer log file lists are that PROJ: Error: proj_create: crs not found and msProcessProjection(): Projection library error. proj error "Unknown error (code 4096)" for "init=epsg:103749",

The ESPG parameters that I had in the older file database are:
<103749> +proj=lcc +lat_1=44.25 +lat_2=44.58333333333334 +lat_0=44.19555555555555 +lon_0=-95.85000000000001 +x_0=152400.3048006096 +y_0=30480.06096012192 +a=6378559.758 + b=6357173.65471281 +units=ft +no_defs  <>

Thank You!
